Slow as they are in coming, I am gradually tidying up the Toupix web interface. As well as including more information about each photo (including author, other people and tags in the overview pages), the backend code is being completely rewritten to an MVC pattern. Once this is established throughout the site, the XMLAPI can be extended to offer the full functionality that Toupix has to offer.
If you've not yet tried out Toupix, please sign up and have a go (it's free to register...). The final presentation of the project is in a few weeks, but before then I will be demonstrating it at the J2ME / Mobile workshop being held in Plymouth's Portland Square building on April 27th.
