thats a useful tutorial for making your own. Ill try the image making section first, I really want to see it in action. Then ill try to make mine not session dependent somehow?

I tried it this is what I got in plain text:
‰PNG  IHDR
��߇€IDATxœíÔA À0À¿çÃ?²¤U°×öÌ,€‚ó;à•a
†d�aX@†a
†d�aX@†a
†d�aX@†a
†d�aX@†a
†d�aX@†a
†d�aX@ †a
†d�aX@Ʋi9éÎNÓIEND®B`‚

I got this instead when I changed it to making a jpeg.
