single gallery web page

To start with I want one webpage built. This page will access a Postgresql database for the images to be shown. This webpage will show one image at a time centred in the div. There will be an image name displayed along with the gallery name. I have a working basic external css stylesheet setup already. I have a proposed database structure also. The menu will be transparent until mouseover. So too the navigation buttons when required. A fade-in pop up text box for image data will also appear. The images will fade to grey. The images should load while the previous one is being viewed. Any techniques to speed up the responsiveness of the page should be considered and discussed. No Flash. SEO friendly. Only common, stable, open-source software to be used. eg ajax, jquery, php. Clean programming using the best practices available. External CSS style sheets if possible. Images will be of a different size so auto positioning is required. Auto downsizing of images needed in later pages (creating thumbnails) Graphic design to come. Other pages to come. Website / webpages to be obfuscated when complete. No links to social media required at this stage nor any shopping cart. All details should be discussed and any suggestions made when contract approved. I have attached the basic files that I'm thinking might be a basis for this project. I am based in Australia
