How can I correct this error in a tree?

I have seen tutorials, but I don't know how to correct this error, when creating a tree in Y I have 2 areas that match the textures, but another one has the wrong textures. Here is the example

don't use the flipped texture at the backside of the poligon.
UV map the tree so it looks the same from all three angles.

Thanks Gunnar, but I don't understand the UV mapping thing.

Thanks Gunnar, but I don't understand the UV mapping thing.

Hope this explains it a bit better:

btw: I can't help you how to do this with Blender since I use Max.

Thanks Gunnar, because I'm only doing it in 3Dmax, I usually use it too and I'll try if it works for me.
