I thought this one would make neat desktop wallpaper. I framed it this way on purpose, putting the background out of focus, with the butterfly in the lower right corner being in-focus. That way the main interest of the image could be in the corner, perhaps not covered up by an application window.

If you want to use this as desktop wallpaper, click on it a second time to get the full size version, then right click on the picture and select 'Save picture as'.
