Yes, I can view the image, but loading never ends and if I try to stop it, the above error appears.

Answer 2

A:

After a little digging around on Google I found this bug report. It seems that the GD library is less tolerant of buggy JPEG files than other programs. The solution suggested was to set GD to ignore JPEG error's before processing the image, like this:

ini_set("gd.jpeg_ignore_warning", 1);

Hopefully that will work for you. One other potential problem you may run into is to do with memory. It seems that GD holds all images in memory as bitmaps once they've been opened. This means that a 5MB image can actually consume more memory than a single PHP thread is allowed, resulting in a fatal error. I had this problem with some image uploads and had to reduce the maximum file size I allowed to get around the problem.

Good luck and hope that helps.

There was also this comment in the manual: "If you get this error: "Warning: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error" then check the JPEG files. If they are saved in CMYK format (instead of RGB) then GD will fail to load them (tested with GD 2.0.12)". Finally, there were comments about images shot with certain cameras which wrote extra information into the JPEG headers causing problems. Hopefully one of these ideas will solve your problem.
