Use of a Photo taken by a friend

My question is regarding rights for use of a photo.

A friend of mine did me the favor of lending me a camera to take some pictures that would be used for posters and flyers and promotional materials for my husband's music performances and upcoming album. We told her that this would be the purpose of the photos and so we needed a camera capable of taking high quality photos. She agreed to lend us the camera. When we went to pick up the camera, I was unable to take the photos myself and she volunteered to take them for me. She took about 9 photos of my husband in public places.

She gave me the memory card of the photos and expressed no interest in the photos. She recently sent me a request saying she no longer wished for any of the photos to be used and that she wanted them removed from the internet and and all propaganda. We said we would remove the photos that were in our control to remove however, we could not control the photos that were already in circulation.

My question is Does she have the right to do this. She is not a photographer and does not make a living taking photos. She was not contracted or hired to take the pictures. It was done as a favor as I was indisposed and not available to shoot the pictures myself. She was advised of what they were for and did not ask for any compensation or notifications regarding the use of the photos.

Thanks for your advice.
