Not really sure how to help you with your scanner . . . you just scan them and then save them onto your computer . . .

Then you'll want to open an account with Imagestation or Photobucket . . . upload your pics to their site . . .

Then when your pics are on there, you can right click the picture, click properties, and copy the URL address (ctrl+C) . . .

Then in your new message, you'll click the IMG button (up under the Bold & stuff) . . . and paste it into that box (ctrl+V) . . .

Easy enough, right?

Good luck.
