Check http://www.imwrapper.com/ for icon set names. The default is ’standard’, which is the first icon set on each list. All protocols also have ‘default’, which is the icon set actually used by the canonical clients. To find the icon set name, check the URL of the images in the set. For example, if an image’s URL is ‘http://www.imwrapper.com/images/icq/bevelled/offline.png’, the icon set is ‘bevelled’.
