How can i find pictures of my retired racehorse?

I have a retired race horse that i now ride in jumping and dressage. I'm looking for pictures and maybe articles about him online but i have found nothing. I have found some stuff about his sire though. His name is Lion at the Gate and you can look up his pedigree on http://www.pedigreequery.com/. All i know is that he was raced in seven races, one of which he placed first and another he placed 3rd. So i would really like to find some pictures. Any suggestions? Thanks:D
