I've just posted in the Sarah Silverman thread
Post here:
Basically, with the original 4chan pic I used the stegojs site ppl linked to and the password 'silvermansarah' which gave me the file dinfo.doc
Dinfo.doc is a plain text file that contains the code in the attached pic..
Hopefully a codefag can explain what it means/use it to decode the hidden message in the Silverman pic
