I haven't had much luck with the 90s pictures. I know there are some on AdventureRun's website at
http://www.adventureran.com/facepacks.htm The pictures are somewhat lower quality but they are better than nothing.
As far as 80s pictures I found quite a few facepacks and combined them all into one. You can download it at
http://classicmlb.simleagues.com/ClassicFaces.zip Now I did NOT make any of those 80s pictures, I just found them from links on this message board. The picture quality is pretty good and I suggest using them if you are looking for 80s pictures.
Hope that helps!
