custom image/user script

I need to make me a image script, whether it be from scratch or a script that has been made. Basically i need it to display pictures, for my site. I sell home furnishing products. I want the script to use imagemagick or gd2. It will be displayed on the body of my site (the white part). royaldesignsinc.com. Also it will have the ability to add and delete categories and sub categories. You do not need to input these albums, just if it makes your work [login to view URL] will be 2 different views..a catalog and regular. The catalog will display the index or thumbnails of the files with will automatically come up in a new window. The regular view will show she products , 4 by 4, 12 on a page. It will have automatic page number creation and have 2 lines on the bottom of the picture...the name and price. When it gets clicked on to a bigger view it will have the description and the price and name. The images are going to work like this: I can tell the script to retrieve picture from a specific directory. The pictures with a 1 in front of them will be thumbnails and the pictures with a 2 in front of them will be the larger versions. I want there to be an option to use the automatic resize. Adding to this script i need there to be a login on the home page so they user and register and have to be approved by the admin, on an admin section of the site. I want all the information and user and etc to be in mysql, encrypted (the passwords). The image part of the site will have an admin section. So i can tell the script where to retrieve the images from and all other options. I might need to add something but for right now thats it. A gmial invite will be given as well.
