About the pics, the first thing I did was try each of the 3 provided pictures. When none worked (they would show up as my signature, but no text on any of them), that's when I started editing the file (all I have done was resize).
All files in the ./signature folder have the same permissions as my ./lib folder (where the "captcha" image and php file are stored), so it doesn't appear to be permission related (unless I need more than rwxr--r-- permissions). Also checked ownership, still not working.
