the image is probably copyrighted and id rather not post it publicly, can i send it through normal email, like yahoo? do you have an email address? if not ill just flickr it anyway
You will have to put the diagram up on a photo sharing site like flickr and then copy that url into the message you send me. You can also try putting it into an email but that might also ask you for a url site of the diagram. The url would be something like http://www.flickr.com/photos/your picture #. Google picture sharing websites and you will find others besides flickr.
