How do I download photos for historical players?
 

I just tried going to Add-ons Central, and it's essentially dead; all that are there are three skins folders. You used to be able to get team colors and logos, and photos of many of the players, but this was long ago — meaning before Add-ons Central existed.

Does anyone know if these are still available, and where?

If they are still available, how do I get them into the game?

If it makes a difference, I'm playing a 1905 MLB season.
