FanAttic sells licensed 8x10 photos of current players, usually $7-$10 each IIRC. You could also download some high-res photos and print them yourself at Costco, not that I’ve ever done that
I think 8x10 prints are $1.50 each.
If there is a specific player or photo you’re looking for there are some tricks to finding high-res images online for “free”.
