The messages already says it:
Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]:
'C:\ModelMayhem\Source/userphotos/8_48_R.JPG' is not a valid JPEG file

But I open this file in photoshop. It works no problem.

Photoshop also "repairs" broken JPEGs, PHP does not do that, and will never do that. I bet if you re-save it in Photoshop PHP can read it as well.

I re-saved in Photoshop, and post again it works property.
Thank you very much.

GD does provide a mechanism to be more tolerant with broken jpeg images.

Using error_reporting(E_ALL); while developing would have told you what's going on. GD did report some errors in the jpeg codec. Some of the jpeg errors are recoverable, like those in this image.

You can change the behaviors of the jpeg codec using gd.jpeg_ignore_warning:

ini_set("gd.jpeg_ignore_warning", 1);
$im = imagecreatefromjpeg("test.jpeg");

$im contains now your image.

ini_set("gd.jpeg_ignore_warning", 1);
This code is useful. Now I can make sure that my page always works.
Thanks you for your help.

in case of a "recoverable error" i expect that a *WARNING* don't lead in the following code be broken for several reasons:

* it is just a warning and not a fatal error
* read the source image works
* the broken metadata of some cameras are removed in the gd-generated thumbnail
* the current behavior breaks the intention of gd for resize images

$src_img = @imagecreatefromjpeg($src_path);
if($src_img)
{
 // code to resize an image
}
else
{
 return false;
}
