Add a custom favicon to your Blogger blog: "What is a favicon?
The word “favicon” is short for “favorite icon”, and is a 16x16px square icon which is associated with a website (or blog). Browsers which support favicons will usually display a website’s favicon in the address bar (to the left of the URL), and next to the page’s name in a list of bookmarks. Browsers which support tabbed navigation (such as Firefox and IE8) will also display the favicon next to the page title on each tab."
