I've followed the bad documentation and ended up having to Google all the details left out of it to get a better sense of how to attempt to get things working. I got the colorbox functionality to work after an hour.
What that does for me is absolutely nothing. The colorbox opens with no images being displayed. No matter how long I wait or how many times I redo the gallery nothing ever appears.
Plugins shouldn't need the user to edit ANY js file or else we may end up just making the damn plugin ourselves.
