Well, it seems most users have no problems uploading pictures, but one user in particular is having this problem:
Problem running JPEGTRAN:
"/usr/local/bin/jpegtran" -copy none /home/hosting/yorkietalk.com/public_html/gallery/data/500/261schatzie_march_21_2005_jpg.JPG
Error Code: 2
I couldn't find what error code 2 was by searching, and other users seem to be uploading pictures fine. Oh yeah, using vB
3.0.7 and PhotoPost 4.86 vB3 Enhanced.
