You can do pictures from facebook. That's how i've done all my photos.
An easy way to add images is to use the little mountainscape icon when you're in the message box, it says 'insert image' when you float your mouse over it. On your facebook page or any image, right click the image and click 'Copy image url' and then click the 'insert image' button, and paste that url into the box that shows up.
Or, you can type [IMG] (paste image url here) [/IMG] without the spaces, and the image will show up.
