i installed 4images and it looks great. i have hit a snag with thumbnails tho. i have set my thumbnail generator to NetPBM. The correct path is given because i can access the autothumbnailer screen. the problem comes when i try to create thumbnails. its say the operation was successful, but when i check the gallery, the thumbnails are showing red xs (image cant be displayed). i checked the directory in which the thumbnails are created, and the file sizes are reported as 0 in my ftp client. anybody know what going wrong here?
