This picture is from my 6 meg Nikon I set out on a pond for ducks. Thought this turned out nice so will try to put it on in high resolution for a screen saver.
The Nikon takes great pictures and are easy to crop and still maintain high quality. The difference between it and my 6 meg Sony 600 is the Nikon takes pictures at 300 dpi and the Sony at 72 dpi. Quite a difference when you want an 8x10 print.
All my photos are copyrighted, but occasionally I will leave one at high resolution for a screensaver for animal lovers.
I just checked the size of the picture, and it is plenty big enough for a screen saver. Just click on the photo and it will show it in regular size, then right click and then save as. This will put it into your photo program.
