"long" image

Currently the wiki makes it seem to be for horizontal images (since we're practically guaranteed some vertical scroll on any post), and while "long page" sounds like a downhill scroll, could the wiki be changed or a different tag ("tall_image"?) be used for vertically extended images?

I'm tno adverse to this idea. I'm sure there are ways to approximate this with meta-tags and such but tall_image is a bit easier to work with.

I'd suggest we use long_image for images wider than 16:9, and tall_image for images narrower than 9:16. This could be useful for people looking for wallpapers, as it would screen out the long comics and the like.

What about wide and tall then? Long makes me think post #113148.
