Dr. Corda, great! You have probably already seen Dr. Libardi's follow-up, it was twins. Sorry I took us on a wild-goose chase into the "double bleb", but then we wouldn't have you image if not.
The best way to upload is to go to:
http://www.obgyn.net/us/us.asp?page=cotm#Informal
and follow the instructions... or you can just email them directly to me.
Thanks, Terry
