Thanks for posting, I am sorry to hear this is happening. Can you help with some additional information?
- What email client are you receiving the Autoresponder at when the images don't display?
- What the the name of the email you are testing with so we can take a look?
Perhaps its simply a case of images being disabled in the email client.
Test the email in Gmail if they work, that's what it is.
You'd be surprised how many folks are not aware of this issue.
