Deleting/replacing aircraft photo

Greetings, please advise how to remove and replace an aircraft photo. I want to delete and replace a photo taken by a previous owner. Have uploaded newer photo and have tried to “vote” on it. But the votes never change. Please help…

Hi, Was there ever a resolution to this issue? It would seem logical to have the owner of the aircraft have some say in which picture was used for their respective tail number. It should really be part of the profile.
