In addition to the post about the usage of other board images I just wanted to show you this special board. It's a combination of all the standard board images currently available.

It also shows that when you want to create your own board image you are not obliged to create 2x2 squares and you can even design a complete board.

The position, by the way, is really a mate in 262 and the first move of the solution is 1.Kd6.
