In Image library, you can upload images for your website and store them in folders. On the Folders tab, a root Images folder appears. You cannot edit or delete this folder, but you can click Create a new folder to add subfolders as necessary. You can also create subfolders within subfolders to organize your images, and you can move, rename, and delete folders as necessary.
After you upload images, you can display them throughout the website.
You can also allow website users to upload images.
Note: On the Settings tab in Sites & settings, you can require approval for the images that users upload. Under User Image Options, select Require approval for all images uploaded by users. When you select this checkbox, you must approve images before users can post them on your website. You can also limit the number of images users can upload, set a maximum file size, and select a default folder. For information, see Site Settings.
