extract all images from spam folder?

[Chris Yuzik]

We have MailScanner set to quarantine all the spam messages, and in 
/var/spool/MailScanner/quarantine/<date>/spam there are all the messages 
as one file for each.

What I would like to do is extract all of the attached images from all 
the messages in the folder and have a look at them. Would also be useful 
for testing fuzzyocr. Is there an easy way to accomplish this from the 
shell?

Thanks.
