Help classifying some mail as Junk mail

Question

I keep getting mail that doesn't have a subject or message body, also the sender address's are always different. Can anyone tell me how to classify these as Junk Mail? Thanks.
Here are some examples from this morning: All of which have no subject or messege body. Thus nothing for me to take and classify as junk.

Most likely these are spam with perhaps a graphic as the body of the "message."
More and more Mac people are receiving these if you have been reading these particular posts on this very topic. This is one main reason I have come back to the discussion area.
You might try to find a commonality (if this can be found) among the emails, if there is any text at all within the body, or in the "View Source."
I have resorted to making a rule for "Sender is not in my Address Book" and "Sender is not in my Previous Recipients" to be declared as "Message is Junk Mail" and to delete them.
Hope this sheds the light you need, Paula
