You can use one of these pictures taken at the reservoir as a background to your desktop whether you have your screen resolution set to 1024x768 or 800x600 1280x960 or a widescreen 1440x900. If you don't know your screen resolution, try this - Right click on your desktop and choose Properties, then click on the Settings tab.
Choose your screen resolution (choosing the wrong size works, but the
quality will suffer). If you want a customized size, let me know and I
will see what I can do.
