I am trying to change the appearance of my desktop on my newly built media center pc. I have added some website shortcuts (Hulu, Teamcoco, Grooveshark, etc.). I am wondering how to change the icon image on a desktop. I've have searched online and found nothing. In Windows/Ubuntu it would be as simple as right clicking on the icon, selecting properties, then selecting a new icon. This doesn't seem to be an option in Linux Mint 12.

Is there any way to do this? Thanks in advance
