Hey Tex! Welcome to the game.
I went through the same initial disappointment that you did, but after going through the effort to fix, realized I probably didn't care as much as I thought I would!
But here's what I did. Start here and follow the instructions:
viewtopic.php?f=285&t=32477That gets you the player pack from 2020-21, which is approximately 80% of the league. From there, I went through to any recently drafted rookie I was particularly interested in "seeing". I went to NFL.com, snipped a 300x300 png of the player's headshot. I then saved that headshot to the same data/images/players file as the others. Use the file nomenclature "firstname_lastname". Then eventually you will see that certain individuals have the exact same name (example: Josh Allen). What you will want to do is rather than use the "firstname_lastname" you will want to use that particular's player ID number. You can find each players ID within your league file (to be honest, that exact location is escaping me but if you've made it this far...I suspect you will be determined to keep going).
Eventually, in a couple years, a number of fictional draft picks will join your league and you'll start identifying the "OGs" based on seeing their real picture. At least that's where I'm at.
Good luck!! Feel free to post any more Qs, lots of great folks on here who have all kinds of good information on this game.
