I need a small singe page web application called "Image Tagging Tool". Back-end logic MUST be implemented in Python 2.7, And all source code should be delivered for further modification. User experience is important without compromising simplicity. Only AJAX is allowed, Traditional form submit and whole page reloading is strictly prohibited. Look and feel is very very important. I want the best user experience with rounded corners of table, image and any right animations you can provide will be much appreciated.
