On one of the forums I'm looking at converting to XF, we've got a photo of the month competition. Each member posts a photo in a thread and then there's a poll to choose the winner. Currently, I've got a vBulletin mod to display the winning pic on the sidebar. However, I'm not sure how I can do the same thing with XF. Is there a way using existing add-ons or simple coding so that I can upload an attachment somewhere and have it display in the sidebar, all from the frontend? Perhaps by pulling the latest attachment from a particular thread? I want to allow moderators to be able to do this, so there won't be FTP/Admin Panel access.
