I originally put this query in the wrong topic. Apologies.
I understand the correct proportions are 960 x 854...but does that need to be at a certain resolution? 72 pixels per inch is okay for the web, but I know you need at least 300px/inch to print a good photo. Is there a certain resolution requirement for the main screen?
Once you are satisfied with the wallpaper you've created, does it need to go in a specificially named folder on your SD card?
Thanks--love reading this forum!
