I've seen this in the forums section here before a little while back, but I can't find it now. Is it possible to prevent the uploading of files that have a default name of strings of numbers and/or letters? If not, is it possible to display a pop-up message when a user attempts to upload an image with it's default name informing them to change it before uploading?
