I own a free image hosting site and we have been having problems with people uploading images that are using tons and tons of bandwidth. We need a system so if say an image went over 1gb of bandwidth in a day the image would not show up or show a default image in its place. I do not want any sql used for this as sql will cause server overloads. We currently serve 22,000,000 image requests a day. We plan on serving over 100,000,000 down to road. We have 1 file storage server and 3 webservers (load balanced) that pull files off it to show on web.
