It depends.

There might be something in the agreement that prevents you from doing that. There might also be something that prevents you from doing that under certain conditions. For example, the photographer might not allow placing their name under the photos that were not edited by them because it might affect their reputation if the edits are not approved by them.

Or you might be allowed to do whatever you want with these photos. It all depends.

You already got done advices regarding camera rentals nearby, but let me give you one more advice. Tell her to make backup of her shots, ideally having 2 SD cards (because they break sometimes) + an online backup on regular basis. Losing photos can be worse than losing equipment.
