Rated 5 out of 5 stars

I thought have this set to auto would bug the hell out of me. But it's much easier to move the mouse off a thumbnail than to click a thumbnail then browse back.

It can be slightly overwhelming on the Google Image Search page because their thumbnails automatically popup slightly on hover then TZP pops up the popup. It would be great if the middleman could be cut out. But it could be argued that is not within the scope of TZP so I'll give it 5 stars.

This review is for a previous version of the add-on (1.5.8.1-signed).
