Astronomy Posters and Space Posters from Hubble and other Telescopes

I was thinking that an interesting idea would be to obtain a collection of some astronomy images from astrophotography of space and the universe obtained with the Hubble telescope and other telescopes. One way to do this that I thought of would be to buy astronomy and space posters, and then post those posters in my room. Below is a slideshow of some beautiful space images from astronomy posters. You can also click on each large image to reach the Amazon page to purchase them:

Besdies buying astronomy photos or space posters, I was thinking another way would be to find images of astronomy pictures and use them as a desktop background or a screensaver, which would loop through the astrophotography images.
