Seems to work just fine for me; scaling image of 7680x4800 @ 23.3mb JPG. The only issue I did have was the fact that, when double clicked from Windows Explorer, it placed the image in C:\Windows\System32. You might consider popuping up a JOptionPane with the full (CanonicalPath) of the output file...

Also tested with image of 1920x1200, scaling to 7680x4800.
