First version of the UVisual

Hello. I deployed the first version of my project (universal visualizer) on the web. Currently it has limited functionality, yet it is possible to use it to fetch images from the flickr and organize them in a sequence of "items".
The page is divided on three sections: top-left, top-right, and bottom-center.
Top-left block has a table of items that can be sorted. Every item may be considered as a "point" in the presentation. When you click the item, the editor of the properties for this item will be open in the top-right block. You can make changes and save them by clicking "update" button. Additionally, in the top-left block you can press the "preview" button to start the "visualization" of the currently selected item. The visualization takes place in the bottom-center block. In the final version there will be an option to run the presentation in the "production" mode, so the user will see only the "visualization" itself - without editors.
Comments and questions are appreciated.
