You can start by posting more information. What version OS? How big are the
pictures (some ISPs restrict the size of attachments)? Where are you
downloading them to? How are you trying to view the pictures? Do you get an
error message? What happens when you try to view the picture? You indicate
that the problem happens only sometimes...does it happen with a particular
sender? Does it happen with a particular picture format (i.e. jpg, bmp, tif,
etc.)?
