Adding A Scrolling Picture Script To My PHP Site

I am running php prolance on my site. I would like to add a custom script so that I can showcase advertising newsletters. Think of a standard letter size advertising flyer (8X11). I would like to have a script that will show these similar to a small slide banner. When a user clicks on any of the slides they will open a new page that will fit the theme of my site. This new page will show the letter size .jpg with navigation arrows to view the next slide. I would like this script to work from a directory that I can upload .jpg's into. This is my wish list, if you have a better way let me know. The new page must fit the theme of my site. I have included a powerpoint file to help explain.
