source larger
When the image at the source is larger (higher resolution) than the image on AIBooru.
This may be because the artist revised the original image and replaced it with a larger version after it was uploaded to AIBooru, 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.
