I am trying to figure out how to let my public users add images through the frontend submission.
Specifically, how to let them add 10 images to the Gallery.

This element id not submittable.

Please open a new question for the other question.

Update:

With regards to this question.... once a business has been listed in the ZOO - how would they be able to upload images to a gallery? Is this a menu item, or....?_

They will not be able to do this using frontend submission as the Gallery Element is not submittable. They can only upload images using the Image Element, but they cannot create galleries.

Thanks kindly.

Zoolanders sells this very good Element for ZOO... You can upload and manage pictures from the backend. Very very powerful.
