Welcome!! What a great idea to scrap while you wait.
So what you want is to unzip your files first. Then as Shelley Rea said you will need a program that can do layers.
There is also a free one (which I have never tried but heard people use) called
gimp.
Once you get your program and your files unzipped you will want to bring in a paper, some elements and your picture. Open a new 12x12 document at 300dpi and start with laying your paper. Then your photo and so on until you are happy with the way it looks. It's a lot of trial and error until you get use to your program and find your style. I wish you all the best.
Oh and don't forget to check
