Just substitute "MLB07.lg" for the name of the example that I used ("RostersV2.lg") in that post.
From what I can see, Cubby has all the images already loaded within that saved game folder, "MLB07.lg" so you should be good to go. Just don't move anything!
You really should not, but if you are still having problems, you could try this help page:
