Our rating scale for images ranges from one star for ‘unusable’ to three stars for “usable” to five stars for ‘very good’. You can use the star rating system to evaluate the quality of the images. Criteria include resolution, colour fidelity, image cropping and alignment, and moiré effects. These ratings automatically influence the ranking when displaying the relevant search results.
With the image viewer at the second magnification level of the images, the respective image can be enlarged and reduced again continuously. The higher the zoom level, the smaller the visible area, but the more detailed the display and thus perfect for evaluating the image.
