To import one or more of the following icons into your zmud client you must first save the icon file to your computer as either a bitmap or jpeg file. At the character selection screen right click on a character and select properties. On the right hand side of the properties window click the square that contains that character's current icon. Click the import button on the bottom of the icon selection screen and select the icon you download from its directory on your computer. The icon will then show up at the end of the icon list and can now be selected for use.
Click on above icon to open icon file page and click download.
Use msPaint or another program to save the .png file as a bitmap or jpeg for zmud to recognize it.
