Possibly restricting photo sizes?

[Angrboda]

Imgfit is your friend. The same way you'd regularly post an image, except instead of just putting img in the tag, put imgfit there. That way, extremely big photos don't end up fucking up the browser.

Except that imgfit blows up small pics to fit the screen size which results in ugly pics and an overwhelming experience even on regular size pics when viewed on a desktop or good sized laptop. If imgfit would shrink but not enlarge pics, that would work, but it doesn't.
