Find out:
Are the recipients able to accept attachments?
if so, can they accept a binary attachement?
What format is the picture you are trying to send.
It should be a standard .jpeg; gif; tif; etc.
Does your attachment exceed Hotmail limits?
I believe in Hotmail, there is a limit to
the attachment size. If you have a free Hotmail
account I think a paid account is able to send
much larger files.
good luck Mahalo,
