Adding Custom Icons to IE

I need an application that will add a toolbar button to internet explorer. I need to have clients pick this up off a server and have it install with minimal effort. The button only needs to link to a url.I need to be able to set the icon and url of the button. The icon and url need to be picked up in the same directory as the .exe. I also am interested in having dropdown list functionality if possible. The dropdown list would just be url links. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform xp, 2000, 98, IE5.5+
