FolExt is joining the many ranks of photo sharing sites. They utilize oAuth and allow you to upload, point to a URL or SnapShot a photo.
There is voting for photos, sharing, and even reporting others for abuse. A pretty much full features site with a clean UI. There is a most viewed section on the right an the homepage updates as you refresh with new pictures coming through the service.
One thing I did notice as I tried to read the FAQ, Privacy or anything else is that all the links pointed back to the homepage, so I could get no other information.
