Picture fixes

[Pibwl]

To finnish with light helicopters, the chart that I've made suggests, that size 3 in the game for Bell 206/OH-58 and Bo-105/PAH-1 is too much - they are no bigger, or actually smaller, than eg. Alouette III (size 2), and not much bigger then Hughes 500, which is bestowed with size 1.

In case you decided to change them, I can list all units affected.
