well when you download from here files are either zip or rar. so they need to be extracted. you can do that by saving the file, then going to the zipped folder and right clicking on it there should be an extract option click that and it'll take you through an extracting process
i'm unaware of any tutorials
if you want to extract rar files then you need winrar you can get that by getting the free trial
charlotte, i cannot tell from the angle but is that one of peggy's pay hairs? it looks like it but i'm not for certain could you let me know which one it is? thanks
