What problems are you running into? Just it won't work?

And unless you saved that jpeg as high high quality, funny stuff'll happen if you try to make it a bmp again.

Well, solved my above problem after even more hours of reading how to use the program and testing.

Now I wonder, am I right in assuming Tesannwyn can texture the landscape for me if I provide some kind of image that it can relate to certain texture files?
