Forwarding email photos?

Hi. . .I haven't had this problem, but an email friend with (I believe) an I-Mac has: When he forwards an email with a photo in it, the photo gets left behind. I can't find anything in my own preferences that would seem to address the problem. Any ideas? Thanks. . .

Yes, forwarded emails don't keep the attachment. Try dragging the photo from the old mail to the new one.

Okay, i'll tell him to try that. Thanks.
