John, if you actually want to make a difference, you'll need to address the PhotoPost crew @ PHP. This software is used by most photo posting sites designed a few years ago and the latest technologies have passed the BB Code and are returning to full HTML for member control features.
Google BBCode for a much larger choice of 'working codes' but don't be surprised if they all don't work because each software distribution is tweaked for the type of site and may have some code features locked for safety and convenience.
