Anyone got a dressage reference I can use?

I'm needing a photo of a dressage horse, preferably doing the 'Side Pass' move, so I can draw it as a gift for a someone.
I really wanted one from behind view, but I have failed to find anything even close to that on the internet lol.
If I use an image from somebody, I would show the drawing once it's finished, and could arrange a free print for payment for using the photo if wanted. I can't get the drawing done for a few weeks, as I have commissions to finish haha, but I would finish it eventually.

If you have a photo which is what I am wanting, please make sure it's clear :) The clearer and larger, the better

Here's one from the front, it's a stock photo and the good thing about it is that credit is not necessary although appreciated so if you want to do give credit to the photographer

Thanks very much! I might just use that :)
