A really quick and dirty hack would be to test if the first two bytes in file are 0xFF and 0xD8.

Nah, that would just be checking if they're JPEGs. I need to test the integrity, decode the JPEG. That got me thinking, what about using a module like imagemagick or something to try to decode and get the error report if they have it? Got something surefire of the top of your head?	[reply]

Well, imagemagick also requires libjpeg, and so does any other tool that goes through full decoding. If I were you, I'd just apply the patch with _setjmp above to the needed tools.	[reply]


Do you know where your variables are?
