Wordpress Gallery Plugin

I need a gallery for Wordpress created for photographers. This gallery needs to have thumbnail resizing and the option to select the thumbnail size and image. It needs to be easily used on multiple Wordpress websites. I need it to function alot like this gallery: [login to view URL] ***Keywords - each photo needs to have its own keywords. **Like this site: [login to view URL] ***Add to cart button, when clicked it opens a window in the same window and shows the available print sizes and prices for the photo. **Shopping Cart that runs off PayPal with the option to specify available print sizes and prices for each photo in the Wordpress cpanel**.** Like this: [login to view URL] ***Gallery Search** ***Photo Uploading** ***Password Protecting** (if it can be done) ***Unlimited Galleries, Categories and Subcategories** ** *The ability to easily put in a title, description and location below each photo (via the cpanel).** Like this site: [login to view URL] ***The ability to have and not to have the thumbnails below the image you are viewing.** Like this: [login to view URL] ** *Previous and Next buttons on the side of the photo.** Like these sites: [login to view URL] [login to view URL] ***Cart and client area, this gallery must have a client area and shopping cart. A place where you can sign up and buy photos upon checkout. (ex. [login to view URL])** ** *Essentially I want a gallery to function very similar to this site:** [login to view URL]
