#useravatar macro not usable with the albatross skin, the required 'avatar' user prop is not accessible

The useravatar macro checks the avatar property in the user object:

        #if($profileobj.avatar && $profileobj.avatar != "")
          #foreach ($attach in $profiledoc.attachmentList)
            #if($attach.filename == $profileobj.avatar)
              #set($hasavatar = 1)
            #end
          #end
        #end

The avatar property is not available from a profile screen (I think). Users should be able to select which attachment is the avatar image. Or, a simpler solution, just use the last image/attachment.
