Yup, that would be nice! But, like Loyce mentioned, I can't imagine theymos wanting to deal with the hassle of hosting the images directly. I've been thinking for a while now about some kind of distributed image hosting, run on a volunteer-basis by interested forum members. I've also been thinking about a new BBCode tag to specifically reference content-addressable images that are being hosted in this way. If that project ever gets off the ground, then I can see a way to make uploading images feel like a completely built-in feature (but without getting theymos tangled in administrative/legal issues).
