Photography Website ASP.net

I have the files for a scripit I need these files to fit into my new design for this photographer's website([login to view URL] see bellow). and for the log-in to work properly (see current site= [login to view URL]) PM if you have any questions How the script works right now.... : The script allows photographer to upload 200-600 photos per wedding. he just uploads a folder and the thumbnails are created. each photo has the option of original color, black and white and sepia, but the photographer only uploads color. the user can preview these options and add to cart. they can choose which size (walet, 4x6, 6x7, 8x11 etc) and this is added to a "cart" which at the end is simply sent as an email the photos will be private for each couple accessed only by logging in with a unique username and password. and all this just needs to fit in my HTML design that I've included (see below img file) additional I would need a small section that will be public which will allow users who come to the site to order his prints of landscapes etc.... without the need of a password. need the script installed and uploaded ASAP
