Where do the little icons that show up in the address bar or bookmarks list for many urls come from?   newagtalk has a green A/T,  Boysungrain has a yellow BG, eBay has the eBay symbol, ironplanet has their black and yellow iron symbol, MFA has their MFA shield, NBC has the peacock,....and here is where it gets a little strange.....my ISP has a eBay symbol, agriculture.com machinery talk has a eBay symbol.

Hoping maybe Ed or some of the NAT gurus will know something about this since his and the one for this site work.
