i just read about this today! apply some water with a brush, then sprinkle, drop, pinch, or throw the salt. Apply your color coats over that. It sould look really bad and "chunky", like it was sitting at the bottom of the ocean. You should be able to scrape away the salt, which will chip away the paint which stuck to it.
Now to get the picture, once logged in, go to "my controls" go to the "personal controls" tab. The last option should be something like persoanl picture or something. Click on that. You should be able to download a pic onto there and it will show up when you post.
HTH, Zack
