A special image for your desktop is a popular theme in the digital scrapbooking world.
Many people add a calendar to one corner of the image, but you can do whatever you want for your desktop.
I often just set one of my layouts as my desktop, but many digital scrapbookers create special layouts to fit their desktop.
If you are a square scrapper, and you have a wide screen, then your layouts may not work well as a desktop background.
Common sizes for a desktop file are 1024 x 768 or 1280 x 1024, but for the best fit, just observe your own desktop settings.
ere is a screen shot of my resolution settings in Windows 7. The size of my screen on my laptop is 1200 x 800, but I could choose a variety of settings.
To find your settings in Windows 7, follow this path: Control Panel\Appearance and Personalization\Display\Screen Resolution.
Another trick is to capture a screen shot using "print screen" (on my laptop, I have to hold down the "Fn" key while hitting "PrtSC") and utilizng the "image from clipboard" under "file" and "new" in Photoshop Elements or Photoshop to create a file exactly the size of your desktop. Thereafter, merely remove the screen shot layer and add your own elements and papers to the file to begin creating.
You can get as elaborate as a simple photo collage or detailed layout or a fantasy scene, to as simple as one of your recent beautiful photos in a frame.
There are many designers who share free "desktop calendars" in the digital scrapbooking world which are similar to "quick pages" which can be personalized as a quick change every month.
Consider utilizing any template and downsizing it to create a desktop image.
Consider leaving a lot of blank space on your desktop background if you leave many files on your desktop so that you have a place to move them to that is not distracting from the image.
Once your image is created, it is easy to set it as your background.
On a Windows computer, just right-click and choose "set desktop as background."
