I wondered what it was you were trying to upload there, Andy ... and this is what I found (by inspecting the webpage for those who may also be wondering):-

Code:
http://C:\Users\Andy\Pictures\dress.png

I'm not sure that a .png file can be handled here (how about that, Huw)? To be honest, I'm not too sure about the syntax you've used, either (in my experience, URL's usually need "forward-slashes" [/] throughout). think

Email the image to me if you like, Andy, and I'll get it pinned up for you. Better yet, send it to Huw! smile

If you don't inspect ... don't expect.
