Emails with pictures?!?

So I tried to send myself a couple emails with pictures that I had taken from the Storm. Problem is, the emails never arrived. I ended up sending them to my email address as a MMS, and they went right through. It is a gmail address.

Is this a phone issue, or perhaps a gmail lag issue? Its been 30 minutes since I sent them, and they are nowhere to be found.

EDIT: it has nothing to do with the pictures. I sent a test message to myself and it didnt go through either. I send a test message from another account to the gmail account, and it went right through. I was also able to reply to it from the storm and it went through just fine.

Maybe something to do with the IMAP setup?
