Thanks for helping me
I have done all that, uploaded the "Xmas" folder in to my "Images" folder. It works to a degree because I can see the logo and the buttons, however there's no snow flakes or any other icons showing including the xmassy backgrounds. I'm beginning to wonder if the styles I am trying to import are not compatible with version 4.0.8 which I am running even though others who are using 4.0.8 have managed to install it after some tweaking.
