This is a short python program which uses PIL (Python imaging library or Pillow) to perform its magic. Cut and paste or email me for the source (Or even better sign up for my page and I’ll use that email).

It takes an input image and places it in a 2048×2048 square with a white background.

I’ve pre-released a kickstarter to fund a photobook.

https://www.kickstarter.com/projects/photorob/wildlife-glimpsed-an-artbook-of-wild-animals-and-plants

About 50 pages of photos and commentary – including where to see these animals and some of their natural history.
