You can tell at a young age if they will make a reiner or at least have a good chance but not from pictures. I have a 2 month old colt that one is bred to be a reiner reined cow horse and I can tell he will be a very nice prospect past his breeding. I can watch him move and tell. It is much easier to tell if you know what you are looking for and look at the horse in person or at the very least in a video.
