Outlook XP -not forwarding pictures

A minor issue that I’ve run into here at the office.

An employee is receiving E-Mail external to our organization, and if she attempts to forward one containing a picture on to another external E-Mail, the picture does not show. We do not strip out pictures when sending (or, the 3rd party responsable for hosting our mail does not), and I’ve tried (un)checking “Send pictures from the Internet”. I’ve been told that mail from any external source to any other external source will make this occur, though I’ve yet to get there and test it fully, nor have I been able to get one of the external sources to send me mail to test it.

So, all the recipient gets is the famous red “x”. Pertinent sections of the source (sent in HTML) can be included for review.

Thanks!
