Thanks for the kind comments

I think I have sorted the attachment/image out, did realize it was a forum feature

Although I think I have picked up a lot doing that map, I would not say I totally understand it all. I have a rudimentary knowledge of how the layers interact and I think i need to experiment, read up and try other tutorials to expand on that understanding. One of the key things for me was just navigating around an imaging program, but like I say, now its time to start really learning and experimenting.
