photoshop images

I would like to add an extra layer to two photoshop files where we can add our own images to the front an ipad smartcover. Please find enclosed the two files (zipfile) we want to adapt. There is also a picture of a real example. Please note that - in the PSD files we also need the small white edge (frame). This white edge needs to be adaptable in color. - We also need to keep the 'profile' (the vertical stripes) on the covers in the background of the inserted picture. - You can just use a hires stock picture as an example on the covers. - The result has to come with a small tutorial on how to replace the image ourselves.
