How are you uploading? Dragging a photo to the reply box, or clicking upload a file? (I'll move our posts to the Forum Help section in a moment - so you can test in there if you like)

That's good - it worked The 'attach' code was in it twice (you might have pressed the 'full-image' button twice?) Try it in the smile photo thread now
