If you want to delete the whole Gallery, what you need to do is:
- Go to the Galleries for Subscribers section in the left-side menu.
- Click the three dots on the right side of the image, and select Delete.
If instead what you want to do is delete a single image within a Gallery:
- Go to the Galleries for Subscribers section in the left-side menu.
- Click the three dots on the right side of the image and choose Delete.
Keep in mind, this action is irreversible, so proceed only when absolutely certain.
