This newer version of Imagus doesn't work at all for me on the Firefox folk I installed it on unfortunately. No image preview was every shown over the images I hover my mouse/cursor on. It's so bad that even the several years-old Imagus extension still does the intended job that this new version was supposed to do.

there is room for improvement, but 5/5 solely for picking up the project.

Works better than the original. Plays videos that the original didn't for example.

Excellent, thanks!
