When the image at the source is larger (higher resolution) than the image on Danbooru.

This may be because the artist [[revision|revised]] the original image and replaced it with a larger version after it was uploaded to Danbooru, or because the uploader uploaded an [[image sample]] or [[downscaled]] version of the image, or because they uploaded a smaller version of the image that actually came from a different source.
