Follow these rules to ensure your thumbnails are approved quickly.
Capture clear, unobstructed views of the level's gameplay or decoration.
Ensure the image is crisp and not pixelated. Use the highest quality settings available.
Choose a frame that best represents the level's theme and style.
Do not include any external overlays, FPS counters, cheat indicators, or menu buttons. The screenshot must be pure gameplay.
Avoid adding text like "Verified by X" or level names unless they are part of the level's decoration.
Do not use Photoshop or other tools to heavily alter the colors or add effects that aren't in the level.
