There's a few ways CT, I'm on an iPad so I simply save image and then here use the attach image button under the reply text box
Alternatively you can save the image and upload it to one of those free image hosting site and paste the link it generates using the image link button (it's the one under the BOLD button with a painting on)
Or you do the same with the imagine link button but put the direct aw address bar code in, only prob with this is if the aw profile changes the photo is gone.
Now the attach image button is here it's much easier, another cool tool added by admin
Ohhh SD beat me to answering haha
