As for hosting the images else where... I considered it, but I've noticed that most of the images are sketches that were intended for the post they were in and I've seen them taken out of context when viewed on their own. Plus I wouldn't be able to re-link them into those older posts (at least I don't believe so).
Let me check my usage, Shaw, and see if we can't work something out. This sort of thing is what Jaynz is about, after all...
