Download Pictures from the Internet
You can also download pictures from the Internet and use them as the wallpaper for your Nook Color.
Turn on your Nook and either enter the password or use your finger to slide the bar to arrive at the Home screen. Press the Center button on the bottom of the page, and then press Web. You will need to be connected to WiFi.
Tap the URL bar and navigate to your favorite search engine, such as Google or Bing. Press Images when the page loads.
Enter the keyword you want to search for, and then click Search. Browse through the pictures and find a picture you want to download to your Nook Color. Tap and hold the picture for a few seconds. Click View from the menu that opens. Tap the picture again and this time press Save. The download screen opens up after you press Save. You can close this out because your image will already be downloading.
When the image finishes downloading, power off the Nook Color to transfer the image you just downloaded to your gallery.
Turn the Nook Color back on. Press the Center button at the bottom of the home screen, tap Extras, and then click Gallery. You will see a list of the pictures on your Nook Color. Find the picture you just downloaded, and tap it.
Select Wallpaper from the menu. You will be asked to crop the picture if it is not the correct size for your Nook Color. When you are finished, press Save. The picture will then become the wallpaper on your Nook Color. Click the N button at the bottom of the device.
