I don't think it's widely known yet, but you can now post pictures directly from your camera roll to your posts as you would on a computer. Just press the paper clip icon and it'll take you to a new window.
Press choose file, and it'll take you to your albums.
Choose picture, an click upload (at the right of the screen)
Wait and then press "close window"
(Just tested myself here)
