I just happened to check the Glacier National Park Web-cams at the right moment.  This photo makes a wonderful desktop background (or screen saver, if you have a screen saver program to plug it into.)

Windows users, for highest quality desktop background, right-click on the BitMap (Windows desktop backgrounds must be in .BMP format) link of your choice and choose Save Target as... to your C:\Windows folder or other location of your choice.

For all other uses and/or operating systems, right-click (or whatever you do) on the JPEG link of your choice and choose Save Target as...(if you have that option), or click a link to display the picture in a new browser window and Save the picture to your disk in the manner prescribed by your browser and operating system and in the file-type prescribed by your operating system for desktop backgrounds and/or other use you will be putting the file to.
