I'm having trouble resizing home screen wallpapers. I have Quick Pics loaded but I need help understanding what editing by aspect ratio and resolution are exactly. I can crop on the preview but with the grid covering the area I'm not sure how it relates to how it ends up on the home screen. It looks fine during the cropping phase but when I save it the photo is gigantic and I only see a large, blurry portion of the pic I want to use. Thanks!
