Marketpress Image File Attachment

I was wondering if there was a way to allow the customer to attach an image file on the checkout page or the product page. Some items that would be for sale as in business cards ect would allow the customer to give us their logo to put onto the business card or other item. I know there's not a current easy way to do this, but I was wondering if you could give me instructions on how to add this in. I've only been able to add the image upload field to the shipping info page, but I don't know how to get it to attach to the email that gets sent out. Any help would be appreciated.
