I didn't realize there was a jersey_fonts folder! I think the program defaulted to the fonts folder, and nothing I was trying in there was working.
Also, I downloaded Silvam14's historical unis logos (

That download had .pngs in the jersey_fonts folder, and those work as well.
Now I get to play with those in GIMP to come up with color matching ones. Pretty sure there aren't MLB ones that would work with some of the pinks I'm using for some of the other teams in my league.
