introduce: 2.0.0
This plugin archives all buddy icons.
This plugin is known to not compile against versions of GTK+ < 2.4. If this is
important to you, file a support request with a copy of the compiler errors
you get when attempting to compile so it can be fixed.
Once you have the plugin installed, activate it in the plugins dialog
(Tools -> Plugins). The plugin will save all buddy icons as they arrive.
To view the icons, right-click on a buddy and choose View Buddy Icons. You
can also use Tools -> Album -> View Buddy Icon and then type in a
buddy's name. This is useful if the person is offline and you have Show
Offline Buddies unchecked or if you don't have the person on your buddy
list.
