Just click the icon you would like and it should install the icon on AIM for
you. Manually, right click the icon you would like. Select "Save Picture
As....", and save it to your computer. (Remember where you save it!) Next,
in Instant Messenger, click on one of you buddy's icons, and it will take you
to the Buddy Icon Preferences (or go to "edit options" or "edit
preferences", then Buddy Icon) . Scroll up to where it says "MY BUDDY
ICON", click that, and select BROWSE. Find where you saved your icon and
select it. Your buddy icon is set.
