What if you open a new message in MSN and attach the picture that way? Have you tried that? My computer reverts to MSN (which I don't even have) if I don't go through my Yahoo account.
I have had AOL , Earthlink and now I have MSN when I try to send a picture from my computer files C drive my computer reverts to earthlink and nothing is sent. I have deleted everything I can find that has to do with earthlink but still the same problem. Also how do I change the name on my sent mail
Thanks Brad
