GifURL is an animated gif URL forwarding and automated rehosting service. It has a bit of a cult following for its speed of discovery and referencing of animated gifs appropriate to message board discussions.
My motivation was a simple frustration -- finding and linking to animated gifs used to take forever. Many sites will show you a gif but hide the direct gif URL in a CSS div background. I decided to build something that lets you reference a commonly used gif without even needing to touch your address bar.
- http://gifurl.com/popcorn.gif performs an http 301 redirect to the most popular gif tagged with "popcorn"
- http://gifurl.com/popcorn goes to a page full of "popcorn" gifs
- http://gifurl.com/http://some-url.com/somefile.gif - rehosts that gif and prompts for tags
Second, GifURL's Gif model handles re-uploading of gifs to a trusted long-term host (imgur.com, falling back to eho.st for larger gifs). Gif addition is so quick and easy, GifURL has rehosted over 1000 tagged gifs since this September.
Third, GifURL has a multi-page website scraping interface that allows for mass uploading, tagging and re-hosting of gifs. That can be found in the gif review controller.
