over at squatty.com there are a couple of downloads in the hacks section that may be of interest to you. the one I use (and have modified quite a bit) allows a user to submit graphics, etc. via a form and the form notifies me when an upload has been made. the form allows for a file, description/instructions, and a screenshot if necessary to be uploaded.
this is not the same as the filemanagement plugin... It only uploads and notifies. Then you moderate and do what you want with it.
it is called
simple uploads
