This only happens with certain images, which when opened in any program are ok, it even uploads to the version of the site I have on localhost with no problems,

To fix try below code snippet-

<?php
...
$image = @ImageCreateFromJpeg($image_name);
if (!$image)
{
    $image= imagecreatefromstring(file_get_contents($image_name));
}
...
?>

<?php
function imageCreateFromAny($filepath): ?GdImage {
    return match (exif_imagetype($filepath)) {
        // gif
        1 => imageCreateFromGif($filepath),
        // jpg
        2 => imageCreateFromJpeg($filepath),
        // png
        3 => imageCreateFromPng($filepath),
        // bmp
        6 => imageCreateFromBmp($filepath),
        // not defined
        default => null,
    };
}
?>

JPEG image should start with 0xFFD8 and end with 0xFFD9

// this may help to fix the error

If phpinfo() shows GD, but not JPEG support, then that's the problem.  You would think that --with-gd would do the right thing since it does check for the existance of libjpeg (and finds it) and add that feature to GD, but it doesn't in v4.4.4 at least on RHEL v2.1, RHEL v3, CentOS v2.1 or CentOS v4.3.

On those platforms, it's *important* that --with-jpeg-dir be *before* --with-gd.  If it's not, GD won't build with jpeg support as if --with-jpeg-dir had never been specified...

It seems that even a small image can eat up your default memory limit real quick. Config value 'memory_limit' is marked PHP_INI_ALL, so you can change it dynamically using ini_set. Therefore, we can "allocate memory dynamically", to prevent those memory limit exceeded errors.

<?php

$imageInfo

= getimagesize('PATH/TO/YOUR/IMAGE');
$memoryNeeded = round(($imageInfo[0] * $imageInfo[1] * $imageInfo['bits'] * $imageInfo['channels'] / 8 + Pow(2, 16)) * 1.65);

                    if (

function_exists('memory_get_usage') && memory_get_usage() + $memoryNeeded > (integer) ini_get('memory_limit') * pow(1024, 2)) {ini_set('memory_limit', (integer) ini_get('memory_limit') + ceil(((memory_get_usage() + $memoryNeeded) - (integer) ini_get('memory_limit') * pow(1024, 2)) / pow(1024, 2)) . 'M');

                        }

?>

This will clean up unnecessary jpeg header information which can cause trouble. Some cameras or applications write binary data into the headers which may result in ugly results such as strange colors when you resample the image later on.

Usage:
<?php
exec("/path/to/jhead -purejpg /path/to/image");
// for example when you uploaded a file through a form, do this before you proceed:
exec("/path/to/jhead -purejpg ".$file['tmp_name']);
?>

I didn't have the chance to test this but I guess this might even solve the problem caused by images that were taken with Canon PowerShot cameras which crash PHP.

This is from the jhead documentation: "-purejpg: Delete all JPEG sections that aren't necessary for rendering the image. Strips any metadata that various applications may have left in the image."

jhead got some other useful options as well...

---  from move_upload_file post ---

I have for a couple of years been stymed to understand how to effectively load images (of more than 2MB) and then create thumbnails.  My note below on general file uploading was an early hint of some of the system default limitations and I have recently discovered the final limit  I offer this as an example of the various missing pieces of information to successfully load images of more than 2MB and then create thumbnails.  This particular example assumes a picture of a user is being uploaded and because of browser caching needs a unique number at the end to make the browser load a new picture for review at the time of upload.  The overall calling program I am using is a Flex based application which calls this php file to upload user thumbnails.

The secret sauce is:

1.  adjust server memory size, file upload size, and post size
2.  convert image to standard formate (in this case jpg) and scale

The server may be adjusted with the .htaccess file or inline code.  This example has an .htaccess file with file upload size and post size and then inline code for dynamic system memory.

htaccess file:
php_value post_max_size 16M
php_value upload_max_filesize 6M

<?php
//  $img_base = base directory structure for thumbnail images
//  $w_dst = maximum width of thumbnail
//  $h_dst = maximum height of thumbnail
//  $n_img = new thumbnail name
//  $o_img = old thumbnail name
function convertPic($img_base, $w_dst, $h_dst, $n_img, $o_img)
  {ini_set('memory_limit', '100M');   //  handle large images
   unlink($img_base.$n_img);         //  remove old images if present
   unlink($img_base.$o_img);
   $new_img = $img_base.$n_img;$file_src = $img_base."img.jpg";  //  temporary safe image storage
   unlink($file_src);
   move_uploaded_file($_FILES['Filedata']['tmp_name'], $file_src);

                 list(

$w_src, $h_src, $type) = getimagesize($file_src);  // create new dimensions, keeping aspect ratio
   $ratio = $w_src/$h_src;
   if ($w_dst/$h_dst > $ratio) {$w_dst = floor($h_dst*$ratio);} else {$h_dst = floor($w_dst/$ratio);}

If you are having a problem getting this function to work on CentOS 4.4 (may appear earlier) and are receiving this error:

Call to undefined function imagecreatefromjpeg()

This is because the installation *does* support JPG by default if you have libjpeg installed. However, the config script finds libjpeg in /usr/lib but it is never successfully added to the PHP build.

To fix this, you should recompile PHP and be absolutely sure to add '--with-jpeg-dir' to the config command. This should appear BEFORE the --with-gd option. Example:

'--with-jpeg-dir' '--with-gd'

If you don't put it before --with-gd, the option is completely ignored.

As always, be sure to do a 'make clean' before a 'make install'. I made the mistake of forgetting to check and wasted 30 minutes trying to resolve this problem simply because I forgot to clean up after myself previously.

The change:

I created a new slideshow script that featured full-screen display. My old "medium-sized" version were only about 600px wide which caused them to luck all ugly after stretching that to modern screen sizes.

--> I created a small script that opens all original images and saves bigger "medium-sized" versions than the once I had.

the problem:

for some reason about 1/3 of all images (not the last third but always the same images) were now labeled as "... is not a valid JPEG file ..." by php

the cause:

still unknown

the solution:

<?php

...

$src_img = @imagecreatefromjpeg($myJPGfile_relative);

if (!$src_img) {

    $src_img = LoadJPEG("http://example.com/".$myJPGfile);

}

?>



Each time the local approach fails the script falls back to loading the same file "from the outside" via the below mentioned "LoadJPEG" script - big thanks to the author!

That worked even though I'm talking about the exact same file on the exact same server. The only difference is that one time it's accessed locally and the second via port 80.

when using this, watch for correct paths relative to your script and the possibly different path relative to your domain.

function LoadJPEG ($imgURL) {

    ##-- Get Image file from Port 80 --##
    $fp = fopen($imgURL, "r");
    $imageFile = fread ($fp, 3000000);
    fclose($fp);

    ##-- Create a temporary file on disk --##
    $tmpfname = tempnam ("/temp", "IMG");

    ##-- Put image data into the temp file --##
    $fp = fopen($tmpfname, "w");
    fwrite($fp, $imageFile);
    fclose($fp);

    ##-- Load Image from Disk with GD library --##
    $im = imagecreatefromjpeg ($tmpfname);

    ##-- Delete Temporary File --##
    unlink($tmpfname);

    ##-- Check for errors --##
    if (!$im) {
        print "Could not create JPEG image $imgURL";
    }

    return $im;

Problem I meet:

When i run following function, which terminates at  

$img = @imagecreatefromjpeg($image_path);

error message is : undefined function imagecreatefromjpeg();

no other code of the script gets executed.

Solution:

In one word, you need to turn on gd lib,
which hold the implementation of imagecreatefromjpeg();

please follow below steps:

my php install dir is: c:/php/
first you must try to find:
c:/php/php.ini 
c:/php/ext/php_gd2.dll(php 5)
c:/php/extension/php_gd2.dll(php 4)

The php_gd2.dll is included in a standard PHP installation for Windows,
however, it's not enabled by default.
You have to turn it on,
You may simply uncomment the line "extension=php_gd2.dll" in php.ini and restart the PHP extension.

Change:
,extension=php_gd2.dll

To:
extension=php_gd2.dll

You may also have to correct the extension directory setting
from:
extension_dir = "./"
extension_dir = "./extensions"
To (FOR WINDOWS):
extension_dir = "c:/php/extensions"(php 4)
extension_dir = "c:/php/ext"(php 5)

Cheers!

i tried the script (with the bugfixes posted later) and still got memorytrouble. most often it is still not enough memory to upload big images, even if it seems to calculate right. so this helped my perfectly:

$newLimit = $newLimit+3000000; (before passing it to the ini_set() function).

extremly simple and maybe not the best solution, but it works for now (you sure can give it less than an additional 3mb, just try what works for you).

First I supposed simple width*height*bpp will be enough, it isn't though; there is some pretty big overhead.

$imageInfo = GetImageSize($imageFilename);
$memoryNeeded = Round(($imageInfo[0] * $imageInfo[1] * $imageInfo['bits'] * $imageInfo['channels'] / 8 + Pow(2, 16)) * 1.65);

With memory_limit enabled running out of memory causes script to crash; above written will tel you how much memory you're gonna need for creating an image-resource out of image-file. So in conjunction with Memory_Get_Usage() and Get_CFG_Var('memory_limit') you can avoid the mentioned ending. (Yet there won't be too many images blocked from processing that would still fit in the memory, as the results of this are pretty accurate.)

<?php

$url = 'RAY_rgb 300x100.jpg';

$img = ImageCreateFromJPEG($url);

// WORKS PERFECTLY
$url = 'http://www.example.com/RAY_rgb 300x100.jpg';

$img = ImageCreateFromJPEG($url);

// FAILS Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error

?>

$row = intval(count($files)+($row_size-1));

(This is the first line in the createThumbTable function.)

So I exclude all Canon PowerShot images with the following check:

    function check_canonpowershot($filename)
    {
        if (strpos(file_get_contents($filename), 'Canon PowerShot') !== false)
        {
            return true;
        }

$memoryNeeded = round( ( $imageInfo[0] * $imageInfo[1]
                                        * $imageInfo['bits']
                                        * $imageInfo['channels'] / 8
                          + $K64
                        ) * $TWEAKFACTOR
                     );
$memoryHave = memory_get_usage();
$memoryLimitMB = (integer) ini_get('memory_limit');
$memoryLimit = $memoryLimit * $MB;

if (

     && $memoryHave + $memoryNeeded > $memoryLimit
   ) {
   $newLimit = $memoryLimitMB + ceil( ( $memoryHave

Of course this doesn't matter unless you're using a strict comparison operator to evaluate the result, but I thought I'd point it out.

Somewhere especially configure --help should have stated that --with-jpeg-dir is MANDATORY if you want to have JPEG support. And even if you did so, it doesn't mean you'll get it. If it's wrongly configured, no error is going to be output, all you get is "no JPEG support". What's more confusing is when JPEG support is disabled phpinfo won't say "JPEG Support: disabled", but just omit the entry so you won't even realize something is wrong.

If you recompile PHP or gd, make sure:
- rm -f config.cache FIRST
- make clean (this helps A LOT), actually you can just delete modules/gd.*, and every *.o in ext/gd. this part actually gave me the best headache
- ./configure --with-jpeg-dir=/usr/lib OR any other directory which contains the BINARY library of libjpeg
- make, make install

phpinfo should now display jpeg support... good luck.
(you lucky guys who already have PHP 5 installed on your server... you don't have to go through all the mess I had)

The work around i found was posted under imagecolorallocate() and prescribes that you first use imagecreate(), allocate colors, and then copy the jpeg into this image.

$memoryLimitMB don't have a value

Add
         $memoryLimitMB = 8;
Before
          $memoryLimit = 8 * $MB;
And change that line for:
          $memoryLimit = $memoryLimitMB * $MB;

--------------

Something similar happens with the script by "JohnBrook at pobox dot com"

$memoryLimit don't have a value

Change:

$memoryLimit = $memoryLimit * $MB;

For:
  $memoryLimit = $memoryLimitMB * $MB;

My solution was intended to solve situations when your webhoster puts a limit on the memory usage; in such a situations ini_set doesn't work ofcourse (even for variables that have 'PHP_INI_ALL' flag in a typical PHP-installation).

Have a nice day

To get around this first check whether the file is a JPEG file using its mime type, if it is not return false.

The problem is caused by gd error output, so by redirecting STDERR to /dev/null all the error messages in it are supressed and you can still use regular STDOUT for your error output.

So, just use
<?
fclose( STDERR );
$STDERR = fopen( "/dev/null", "wb" );
?>
