Ok when you start a new post or reply to one scroll down below the area where you type until you see the button that reads "Manage Attachments" then click on it. It will bring up a window where you can browse and attach the file in question. Just follow the directions on the pop up and your good to go. Just remember after you have attached all your pictures to click the "Upload" button in the lower right hand corner of the pop up window. It will then drop you back to the reply or new thread screen where you need to press "Submit Reply"
