How can I remove wrong pet pics from a profile?

I was spending time at one pet owners home; mostly nighttime, but I also had a walk and a play date with two other dogs. I mixed up the pet owners phone numbers when sending pics and now the pet owner with 2 dogs has pics posted of the night-time pet. Oh my! How can I remove those pics or move them to the right pet owner? Thankfully the 'wrong' pet owners understood since I wasn't yet scheduled to be with their pets, and we laughed it off.
