outlook 2003 won't open pictures in email

[phil-rge-ee]

When I receive an attachment that is a picture (jpg, bmp, etc) in outlook
2003 and I try to open it from the email, MS office picture manager opens and
then just displays the red x, like the same red x that you get when graphics
are missing from websites. I can save the graphic attachment from the email,
to say my desktop, and then open it from there, but I can't directly open the
graphic from within the email. I can only view it by saving it first. Any
ideas why I can't open the picture from email in outlook 2003? (using windows
xp-sp2 and ms office 2003 sp1).

Thanks,
Phil
