Website where you can buy photos of any football match?

It is my dad's birthday in a few weeks and he is a mive supporter of Leeds United and the other week he found a website where you could type in a specific match and there was a photo of it what you can buy. He wanted one of this seasons first match and this is his first year with a season ticket, and he said he's found it somewhere but now he cant remember what the website was. Does anyone know any websites like this where I could maybe buy that photo from?
