Adding an image to a form and have it sent on submission

Hi,

I'm making an addition to a site that is already up and running in drupal. I want to create a new webform that act's very much like a 'tell a friend' form. (I know about the send module, but I'd like to keep everything in one form)

Essentially the form will comprise of an image and the usual input fields for the emails and a short message.

However, I can't work out how to make sure the image is sent in the email. markup displays the image in the form, but it doesn't appear in the email.

Any pointers would be welcome :)

(I've yet to hit the task of having the form send to the right email yet!)
