Which is all very well, and fine. BUT, we're discussing a hobby website showing mostly photographs of model railway things. And one which is fairly easy to find your way around, you know what's coming, etc..
If someone wants a hobby (or profession) in designing websites, then read the RNIB site. Its decent stuff. It won't tell you how to design a good website, but it might stop you implementing one badly. Website design starts by deciding who your audience is, and what they might want to look at. Then, and its much later, do you get near code, code standards, WC3, CSS, Bobby, etc, etc...
However, I think I'm in this newsgroup for model railways, not website design.
