PicAnswers: Image Q&A Community

PicAnswers is a Q&A community similar to Baidu Zhidao or Yahoo! Answers. However, its unique feature is that all questions are related to a specific picture. Users can upload images and ask questions about unknown elements within the picture, which other users then answer. Aside from the feature of being based on image content, PicAnswers has functionalities similar to regular Q&A communities: it includes a classification and tag system for easy search by users, the ability to share each Q&A, and the use of a search engine to find answers to questions.
