What sites do you get your desktop images from?

i get mine mostly from
Flickr http://flickr.com/explore/interesting/7days/ or
Deviantart.com

Back in the day I always used to get them from http://www.digitalblasphemy.com/ - High quality 3D renderings...

http://www.mandolux.com/ has great hi-res images that can span multiple large monitors. The RSS feed lets you know when he's added a new one. See his "archives" for hundreds of images.

I use google image search and then tweak them in photoshop

I use a simple black pixel, on tile;

with this MenuShade;

to give serenity to my desktop.

I use mostly:
