You cannot even use a commercial photo as inspiration for a painting or a quilt without getting permission from the holder of the copyright if you make money on the painting or quilt. If they recognize their photo in your painting or quilt, they can sue you, whether or not you gave them credit and/or you own a copy of their photo.
That's because you are using the art as a focal point, ie copying someone elses work. They won't have a case if you used the art as part of story you tell in whatever art you do.
