Whats the problem? The fiddle is working, I have tested it, and
here have a look[
^]. I selected the image, and before even uploading or doing anything the image's screenshot was present there. What error is being sent to you, you can see it in the Console. Press F12 and look for Console. Every error is logged there, have a look.
