The above is one way. I believe the better way would be to do this.
Because looking at all the images will give you the size and type it won't tell you where they go. If you open a WB in SKS you will see the required images and also where they are placed in each section. You can open them right from the Edit button in SKS.
As Neone6 said look at Kitty's tutorial. It gives you a good starting point to learn some main things. I'm on my way out to play Golf but when I get home I will PM you. Again look through Kitty's tutorial and if you decide you really want to make your first WB I will be happy to work with you.
So check your PM later today and we can go from there. Speaking for the members I think they would all be happy to have new skinners here. You have been here since 2002 so time to get your butt in gear.
