Yeah... but I'm trying to make it so I don't have to moderate it. Doing it that way would allow a user to get around it. I'm trying to make it a feature that users don't have a choice of using or not.
I was thinking about making two codes- [pimg] for post images and [simg] for signature images. However, I'd have to moderate that. I'm trying to make this completely automatic.
www.forums.gamebattles.com does it somehow... but I'm not sure. I worked there for a couple years... but never looked. =P Also, the owner of the site never made any code modifications. He didn't like voiding the support. So he did it all with template and bbcode edits.
