Yes a photo is required but sometimes if the photo is not the correct size or the system for some reason doesn't upload it then there is no photo. I'm sure there are other reasons for no photos. There are people behind the scenes trying to get all the photos put in there but it takes time and if I'm not mistaken then once so many are done then it is updated all at one time sort of like when the checklist is done and the system updates. Before Kevin became registrar there were some issues going on but I don't know enough of the details to be accurate about it.
Only the hybridizer can submit photos so if they cannot get in touch with that person or that person is deceased then they have to try and get in touch with family members and such to get a photo or permission to use other photos.
you could always email Kevin Walek and ask him about it
