You may want to look at
http://groups.google.com/group/communityengine/browse_thread/thread/1a942cea86e4015b
as well, particularly the links in Bruno's answer. His answer pointed

http://github.com/lukemelia/rails/commit/4eecef63ece3927b2a432df217b180c9aa4d3df5,
which I found interesting.
For now I took a not very dry shortcut, by simply defining
def member_photo_url(user, options)
user_photo_url(user, options)
end
