Open the pic and crop it on the phone. When you save the edited version it will automatically be saved as a fullsizerender. If you don't do this, the picture tends to be posted upside down or sideways. send the pic to yourself via email then open the email on your computer. download the pics and then save them to a folder. I keep my folder on my desktop. Once this has been done, you can post the pictures in a post by clicking the insert image icon.
