Most of you know I'm mostly into sound, music and movies. But I also collect images which I use for my computer desktop (or wallpaper). They're collected from all over the place. Some have been modified to my liking, but hopefully keeping to the intent of the artist. Usually just adjusting over all levels so that the darkest is fully black and the lightest is fully white. Of course you can't sell these your self. And if you own the images and don't want them shown here I'll pull them.
	This is my favorite stuff! The National Gallery of Art at www.nga.gov is my favorite site for desktop images. Except for one thing, their photos of the paintings are not at a very high resolution. They do have closeups of different sections which I'll sometimes paste over the low res version. This becomes my personal art lesson. You can see this in the large images where some parts of a painting are sharp and other parts are fuzzy.
	Music codices from The Vatican.
	photo.net. Excelent photography with high resolution images. Since I don't make any modifications to the photos... well, at least none that I think the photographers would approve, just go directly to their site.They also have extensive reviews of equipment and have numerous photo contests.
