I added a favicon to my website—the SMPTE color bars—using the full power of Photoshop to create it.
As defined by Wikipedia:
A favicon (short for ‘favorites icon’), also known as a page icon or an urlicon, is an icon associated with a particular website or webpage. A web designer can create such an icon, and many recent web browsers can then make use of them. Browsers that support favicons may display them in the browser’s URL bar, next to the site’s name in lists of bookmarks, and next to the page’s title in a tabbed document interface
I think urlicon is the best as it sounds like a mythical creature of some variety; whether one pronounces it U R L icon or earl icon. I would also suggest pagicon, for the same reason.
As a special feature of this post, I left the links within the wikipedia entry because I am too lazy to remove them. Enjoy.
