Members will have the ability to add profile information, biography, avatar etc.? We want members to have the ability to upload their own photos, stories, articles. Integrated with current database and display related stories to that user or keywords.? Photo gallery needs to be multi-level,? all photos will be stored in SQL database for ease of management.? Photos will be dynamically sized, and have ability to add photo tags for integration with other website features, forum posts, pages, news, etc Ability for website visitors to rate photos,? Photo search feature (search by most recent, highest rated, tags, description, etc.), Creation of widgets for integration with other website features (random photo, mini-gallery, related photos, recent photos, featured photos), ? Photo title, description and tags integrated with webpage meta tags for search engine indexing/optimization? Administration utility for uploading/managing photos integrated with our current CMS.? The above must be integrated with a website Search Feature, creation of search utility to search all of the website's database-driven features (news, photo gallery, video gallery, membership profiles pages, etc.)Organization and display of search results by type (photo, video results will display as thumbnails, grouping of news results, page results, database results, etc.)
