Feature request: Editing Images

Hi, I wanted to ask you if it was possible to add the possible to edit an image / attachment. Let me explain better, I wish there was the possibility of being able to modify the photo, and not just the text, to be able to replace it with another image, rather than republish it. I have a server, in which I created a game guide, but every time I have to delete everything because the image cannot be changed, and then republished it. It is quite unnerving. I hope you can add this very handy new feature, for those who, like me, make guides on their server.
