To customize iPad wallpaper, there are some simple guidelines to follow. You need to select on a photo enlargement program. This is the most important step in that it will help edit and crop the image to size. Find an image that is interesting to you and one that will look beautiful as a background and select on the export tab in the lightroom. The native resolution of an iPad is 1024x768 though you can be able to resize it so as to view it in portrait or landscape. On the image select 'All Sizes' and download it. You should however ensure that the resolution is higher than 768 so as to stretch on the entire screen. Press and hold the image for about 3 seconds, thereafter, release and select on save image that will appear in pop up image. In the photos application, select the uploaded image, click on the export button and select 'Use as wallpaper'. You can then decide to choose on 'Select Home Screen', 'Select Lock Screen' or 'Set Both' and export the photos app so as to view your new iPad wallpaper background.
