1: Open Google, go to Images (duh)
2: Type in the first/last or both names of the player you want, after that type "epochtimes" and make sure you have the "Large Images" tab clicked... you might have to do that AFTER the initial search, but whatever:

For this Tim Duncan search I got 8 pics, ranging from 747x1200 to 2170x3000 (!!). These pictures are enormous, not all of them are that great but there are a few good ones in there.
Alternatively, if you enter the words Getty Images instead of a players name with epochtimes after it, you'll get a huge range of massive-res pics of random things.
