Working with image galleries published on your website is easy. When you’re editing the page or post where the image gallery is, simply click on the image gallery, and several icons pop up (see the screen shot below.) Choose the pencil icon to edit the gallery. Editing the gallery gives you the same options as you saw when adding the gallery. Choose the X icon to delete the gallery. Deleting the gallery only removes it from the page or post; it does not delete it from your media library.
