Right now, it appears that the only way to delete any art you have uploaded is to load up a game you DM, right clicking an image, clicking delete, and clicking once again to confirm. If you are trying to delete uploaded images en masse to clean up account space, this is very meticulous and takes a long time. I propose a library management tool to go under the "tools" tab on the main website (similar to the character vault.) From there, you would not have to load into a game to see all the files you have uploaded. There would be information like the file name, the image its self, how much space it is taking up on your account, and checkboxes to select multiple files to delete. In case someone accidentally deletes something they didn't mean to, there could be a 24 hour period to retrieve it before it is deleted permanently. Here is a rough mock-up I've made of what it could potentially look like.
