I appreciate the brainstorming
The best solution for me currently would be one that didn't require any change of the img src. Mine are already wrapped in a div id=hahahahahaha so the css #post method is ideal. Just a quick addition to the style.css and I'm gold.
If I could add a clickable link without having to edit the img src tags, that would rock. I'm not sure if the 'expression' will allow that.
