The Steam Deck is a powerful handheld gaming device, but adding artwork for non-Steam games enhances the visual experience. To customize your game library, follow these steps. First, gather high-quality images of box art or promotional materials. Use sites like SteamGridDB to find pre-made artwork. Next, navigate to your Steam Library and right-click the game. Select “Manage” followed by “Set custom artwork.” Upload your chosen image and watch your library transform. For added consistency, ensure all images are in the same resolution, such as 600×900 pixels. This simple tweak personalizes your Steam Deck, making every game uniquely yours.
