Um, I dunno.
Did you by any chance put rootsig.png in your signature instead of sig.png?
Does your host support the GD Library?
Hang on, and I'll try and set up mine, and see if I have any difficulties.
EDIT: I have difficulties telling the PNG file to be a PHP file.
I got my PHP file to work. [
Here], but when I rename it sig.png, when I try to open the file, it asks what program I want to use to download it. I have a .htaccess file telling all files to open as PHP, regardless of extension, so I'm not sure if it's just my host.
