Border 1.5

No permission to download
I first tried this plugin but sadly couldn't get it to work. I contacted AndyB and he gently offered his help to see what's happening. He entered my site, discovered a small bug and quickly fixed it. Also released v1.1 for free. He's a true gentleman and a high-class programmer.
The plugin works best with cropped screen captures, helping to see where the image starts and ends.
