Yeah, I knew .gif's belonged to Compuserve, just surprised MS have had it removed. Presumably so's not to have to pay anyone.
They must hold a licence to use gifs though, as IE does just that.
The patents for the GIF format ran out a couple of years ago, see here: http://en.wikipedia.org/wiki/GIF

The US LZW patent expired on June 20, 2003. The counterpart patents in the United Kingdom, France, Germany and Italy expired on June 18, 2004, the Japanese counterpart patents expired on June 20, 2004 and the counterpart Canadian patent expired on July 7, 2004.[16] Consequently, while Unisys has further patents and patent applications relating to improvements to the LZW technique,[16] the GIF format may now be used freely.
