BUR #7162 has been approved by @nonamethanks.
nuke long_image
I'm not sure why we even have this tag. It's currently autotagged, but we already have tall image and wide image, which are quite different - one is for images that extend past the page downwards, and are mostly readable in their default form, while the other will always be displayed in its fullness (even though sampled down) due to how danbooru samples work. Tall images tend to be comics or posters, while wide images tend to be spreads or scenery.
I just don't see the utility of the umbrella tag when the other two exist and have nothing in common other than some abstract inverse ratio relation.
Submitted pull #4884 which will have to be merged before this can be approved (otherwise the nuke would have no effect).
