What are the photo requirements for a Thai marriage visa extension?

I was told by the Kanchanaburi immigration office that I need a picture of my wife and I in the bathroom (as well as kitchen, front of house, sitting on our bed, etc.) for my annual extension of visa based on marriage. Does that seem right? Is there an explicit list of photo places in the house that needs to be submitted with my extension? Seems strange to request a photo of my wife and I standing in front of our toilet. Thanks.
