ImageFocus — Rezzi

Double-click on any unlinked image on any website to isolate it in a clear lightbox overlay.
Alt + click on an image with link (<a>) also opens the overlay. A normal click follows the link (standard browser behaviour).
Scroll to zoom in and out in the direction of the cursor.
Click and drag to move the image.
Press the ESC key or double-click to exit the lightbox.

If you find any bugs, have suggestions for new features, or just want to say thank you, please leave a short review/comment!

Depending on how images are integrated into some websites, the add-on may not work correctly. This would require writing a separate add-on for each such website.
