I spent about a half an hour taking pictures of my ball python, and this is a good one I thought I'd use as a desktop background for my 20" iMac G5. After creating it, I thought maybe someone else just might want this for their wallpaper, too. I won't get any hurt feelings if no one downloads this (LOL). Just wanted to share and also ask if anyone else has any wallpapers like these.
There are four formats; approx. 1680x1020, approx. 1280x900, approx. 1024x750, and approx. 800x530. All measurements are in pixels.
1679x1117 pixels - for a 1680x1050 resolution screen (or close)
1024x681 pixels - for a 1024x768 resolution screen (or close)
1280x851 pixels - for a 1280x1024 resolution screen (or close)
800x531 pixels - for a 800x600 resolution screen (or close)
Choose the one which best fits your desktop, download it to your desktop, and set it as the wallpaper.
P.S. If I had made the measurements exactly the way I wanted them, the image would be a little distorted, but it should show up fine on your desktop anyway.
