Those are called favicons. You will need to make one. You can go here (http://www.chami.com/html-kit/services/favicon/) to get one made from an existing image. To find out how to put them on your site go here (http://www.favicon.com/). You may find this link (http://www.favicon.com/index.jsp?id=Internet+Explorer#3-1) helpful as well.

If you mean replace the application's icon, no you cannot. It is part of the browser and cannot be changed.
