MyBB Community Forums

I know there is the tag [attachment=aid]. However this does not work in post that attachment is, I would like MyBB to parse every attachment tag to an attachment code in any given post. For example, if you upload an picture in an new post, then you want it to show in the first post aswell as the last and you would want to show it as an thumbnail aswell. This would make it alot easier, well for me anyways.
And maybe add an list of all the attachments the user has uploaded to the forum?

Maybe this has been done, still just wanted to say it
