There is a bug in the current release of JQZOOM. If you click the thumbnails to do the image swap, it works, but if you click the thumbnail of the image that is already loaded, the loading screen pops up and nothing else happens. Anyone know how to fix this? Please PM me if you do, thanks!
OK never mind - It looks like this was fixed in the patch that just came out this month. If you were having the same problem, checkout version 2.3 /Thread
