Inserting Image in eMail Template

I am trying to insert an image in eMail template using below Image URL: <img src="$dnb_web_signature_white.gif" alt="" /> But when eMail is sent the image is not getting displayed because the URL is changing to <img src="ui/images/icons/DNB_Administration$dnb_web_signature_white.gif" alt="" /> When I tried to do the same in my development server I am able to get the email with Image. Could you please let me know if am missing something in UAT environment?

In the email body there should be an image tag without path, so <img src="filename.jpg"...>

Taking HTML from an RTF field in Mendix means replacing the image tag src contents before sending the email.
