It doesn't matter what anyone else thinks if you like it, but I have a horse and I think Koy Image would be a cool name. You could call the horse Koy for short. If you are buying a horse with no name, then choose what ever you want, but if not, then you should probably choose a name close to the current on so the horse doesn't get confused or have to learn another name. Another cool name if you are planning on showing the horse would be "Sky's The Limit", and you could call them Sky. You should do whatever you want, the sky is the limit for horse names. I don't think your horse would care what you called them anyways.
