Click on a thumbnail in your search results to view an image. On the detail page you can zoom and pan, view the image full screen, and see metadata about the image such as the name and creator of the work, the medium, creation date, and more.
You can zoom into images to see a detailed view of part of the image. Use the scroll wheel on the mouse or the buttons that appear when you hover over the image to zoom. These zoomed or detailed images can be added to a group just like full images can be. When you click the orange ADD TO GROUP button, simply choose "Add detail view" instead of "Add item."
