A user (jaberg) brought this to my attention and I think it's a good idea.
If we had a way of showing what media we have uploaded to this site and a link to be able to re-use it then, if we want to put the same picture in two different threads, we can link back to the first one rather than uploading the same image twice.
I am sure it's possible, we just need a way of 'exposing' it to the users.
