Marcy,
I think you mean Beyonce. 
But aside from other people, you can
always use any random photo or image you like or want to promote, it
doesn't have to be a photo of you. There are some sites where you can
design your own avatar [see http://en.wikipedia.org/wiki/Avatar_(computing)
], including Yahoo -- http://avatars.yahoo.com/. I don't usually use
my Yahoo avatar, but I made one (see below).
Love & Liberty,
((( starchild )))
