Shows just fullsize Image with hotkeys & without pop-ups on many image-hosting sites
There is already a script which does exactly that, try searching around here on greasyfork

Hover Over Thumbnail/Save Image
Would it be possible to show full size image from the thumbnail like from a forum post with several thumbnails? Maybe also able to save full size image from said thumbnail?
