Unfortunately this would not be easy to do for this addon, because the entire interface and all of the code revolves around utilizing a single FileSet -- whereas including separate images for a rollover (or even a separate image for the thumbnail vs. the enlarged image) would mean having to choose 2 sets of files (and all of the possible problems that would ensue -- what if one fileset had more or less images than the other? how would you sort both at the same time so the corresponding images stay associated with each other? etc.)

As far as I know, the best solution for what you want to do is add a Layout to your page and then individually add Image blocks to each cell of the layout, each with its own rollover image.

Sorry I don't have a better solution for you :(

Hey Jordan.
Thanks for the speedy response
Hmmm. yeah I thought it would be easier said than done!

The problem is that I would like the Fancy Box trigger on the click of each image... and not just a rollover state. Never mind.

Thanks
