6348 Image gallery/display pictures

Hi, I am looking for a progammer to convert my current MSN Display Pictures([login to view URL]) section into a much advanced and better one(but not so high-level and complicated). for this i have created a list of features required: What i Need: * search engine friendly URLs(display-pictures, display-pictures/animals/Page-1 {as you can see it is already added on the website). * Latest Entries and Top Pictures by Voting (currently its by # of downloads, which is somehow useless, and i will need to add it to the main page). * Admin panel to add/manage/edit/delete pictures and categories. * Will automatically resize images(see below for details) * Support for sub-categories would be good(but not compulsary). But atleast 1-level sub-categories would be great. * Should use some sort of cache thing to lower the database queries and server load. (MUST REQUIRE) how will it look like: * On the MainPage i will be needing to add top and latest enteries(as mentioned above). * Each Main category will have a thumbnail image(can be seen on the website) * Sub-Categores will be listed on the top(below page heading) of the main category page) * Sort by Latest Added/Top Rated (default will be top) on every page. * 20-30 pictures would be shown on a single page (48x48pixels or other each) with space to add ads in the middle. * Clicking the iage will open the full (96x96) version with Download and Vote(with current rating) options. (download will be handled the same way currently it is) above given your own ideas will be highly appreciated. you agree to provide support without any additional charge until the script is completely integrted to my website. * Links/refrenses to your previous work is required. * Payment will be made after the work is completed(or after testing the demo). Regards, Zahid
