I would like this as well, if it is something that is possible.
I understand not having the image show up automatically in quotes (as that takes up so much space) but sometimes people quote things with images from far before and it can be quite difficult to flip through everything to find out what picture they are talking about.
both of these solutions will only work if the image isn't already part of a link, that's the main reason I didn't do that. I'd have to write some sort of code if a URL tag was started, but not ended, prior to the image. I might do that, but it's not just the matter of changing a single line of code in two seconds.
