In gallery view, hover over the collection to see a description. Shared admins can also choose a preview image for the collection by hovering over the image and selecting Update Preview Image. Any file from any collection can be used as the preview. Search, filter, and sort to find a file, and to crop, rotate, or flip it. If a preview image is not selected, a file from within the collection will be randomly selected as the preview.
When you share a collection either publicly or privately, anyone you’ve shared the collection with can select their preferred view.
