I’m currently on a wallpaper binge. I gathered dozens of Google images with a resolution of 1290x1080 or higher. Using the drag-and-drop method, I placed the images in a Wallpaper folder I created on my Desktop. When I go to System Preferences > Desktop & Screen Saver to select and view them, they’re out of focus and pixelated. Is there another way to select the images without losing resolution?
