I just updated the plugin this morning and suddenly non of the single images are popping up when clicked. You're just directed to a page with the image alone. Also, before I updated, the price for Pro was $18 and suddenly it's $24. I wouldn't mind upgrading, but I was testing it out before I bought it and now it doesn't seem to be working. This particular function should work in the lite version. I'm using it on most of the pages of this site.
