Custom Backgrounds

[picea892]

Hi all

I recently have been experimenting with GDI backgrounds, and these examples are really a continuation of this Instead of experimenting with gradients, this example focuses on fading in a background with the intent of making borders, shadows and glow effect. Include the picture in the same directory as the script

Any improvements and suggestions are welcome.
