One of the easiest ways to free up storage space is to delete unused images in your Media Library.
How to remove the images from your Media Library
- Click on Libraries & Tools.
- Click on Images under Media Libraries.
- Pick the images you want to remove from your library.
- Click on Delete Selected Items at the lower right corner of the library.
- Confirm the deletion by clicking Delete.
NB!
You must remove the images you deleted from your galleries to avoid broken images. (The images may be viewable for up to 30 days due to global cache.)
