Buzz Light year allows you to email your picture anywhere.
I believe Innoventions in DL had the email cards similar to the Innoventions in Epcot. I just dont spend enough time in there anymore to see if they still exist.
I do know for sure if you visit Stitch on the second floor he will take your picture. Its in a web site you pick up the picture from so not email but you can send the link to anyone with the code to view it for free.
