Picture Message (MMS) to E-Mail

Hello, I have the UX245 cell phone by LG. I have figured out how to take a picture, and I know all about SMS (text messages,) but I cannot figure out how to send a picture message to my Gmail account.

I have correctly typed in MYACCOUNT@gmail.com with the attached picture, and clicked send. Immediately after, it says "Message failed to send." The picture is small, about 10kb or something... and the limit is UNDER 5 MB.

Any ideas on what could be wrong?

and u already have Pic Messaging on your account? (ie. Pay as you go, or the package)?
