On very few images, the "download a comp" button below the image preview is missing. In this cases we do not have a dedicated comp image for this photo. We recommend to use the preview image and download this instead (right click and download image in most browsers). On MacOS you can actually just click and hold and drag the image to your harddrive. Keep in mind to store the unique Image ID as well to find the photo again in our database i.e. Image ID:ING_17215_08350 in the case below.
