Image in email not working

Hi,
I am trying to send an image from opencart email (simple image using the upload image function), but its not displaying in the email (gmail). So obviously I cant send HTML with images. Any ideas?

Thanks!
Cheers.

check the mail source and take a look at the mime-type (compare what you find with specs from wiki or other sources). i do remember some sort of trouble i once had with that - a pitty i just changed it in my shops source and can't recall in which file

hth - greets,
