Relevent Jsfiddle: http://jsfiddle.net/bWxYd/5/ (credits to Matt McDonald)

-Should work for the first image under "Rage Faces" tab.

Bonus: Can you tell me how to get rid of the background changer without getting rid of the image opacity changer.

Not sure why (only checked it quickly with Firebug), but it looks like a css thing: If you declare a position for "linksHolder" and "tableHolder", they are visible.

eg.

#tableHolder {position: relative}
