During the initial installation of AOL onto your computer, the Graphics settings were automatically set to "Always Compress Graphics" which distorts images viewed online or saved to your desktop.
For the best picture quality available, please be sure that this setting is changed to "Never Compress Graphics" before installing one of these wallpaper images.
Depending on your AOL version, you may find this setting by clicking on:
Settings
Preferences
Internet Settings
Web Graphics
Click on "Never Compress Graphics".
