Image Overflow allows you to upload images from your local computer or link to image on the web.

You can compete with others to tag your images. Login with your Google account and suggest tags. If your suggested tags match any suggested tag by other users then both you and the other user gets a point. Your points will be displayed in the toolbar at the top. If you don't want to log in, you can still search and tag, but your points will not be tracked
