under the message box it there are two buttons, one says post quick reply, the other says go advanced. you click on the one that says go advanced. that will open up a differant screen, and if you scroll down you will see "additional options" and a button that says "manage attachments" click on that button and a pop-up will appear with a button that says browse, click on that to access the image from your computer. once youve got the image, click on the button right next to it that says "upload", close the window and hit the submit reply button like you normally would (below is what happends when you do it that way)
