Cached items do usually expire after a certain amount of time, or after some other limit is reached (number of files, amount of space used).
It's possible that what I experienced was affected by browser caching. But since it was a problem of an image not being loaded at all, rather than an old version of the image being shown, it seems unlikely (there was nothing for the browser to cache).
> So I make a new post and edit it 25 times after posting it; does DW retain any/all prior versions (actually, I've always wanted to know this)?
Keeping multiple copies of each post would increase storage space a lot, so I doubt it. I have wondered, when one deletes a post, if it is actually deleted, or only marked as deleted and then no longer shown. But since I haven't heard of there being an undelete function available, there wouldn't be any reason for it to be kept either.
If DW is caching on their server side, I don't think client side tools could help determine much. But you could upload an image, link it in a post, then update the image and keep checking back to see how long it takes for the post to show the new image. That still wouldn't tell you though if the caching was time-limited or otherwise.
