Adium plug-in saves contact icons used over-time and includes an icon viewer. The software is free.
Icons can be copied from the album with ease via Drag&Drop. To make things even more accessible, this plug-in currently offers localizations in English, Dutch, German, Portuguese, Finnish, French, Spanish, and Swedish.
However, if these options don't meet your needs, further translations are welcome. This album software is a great asset to those looking to easily manage and view their contacts' icons.
