AJAX Dragable Content (Photo Album)

We have a site that contains albums - photos for different users. We want a function that enables them to arrange photo location/ordering by drag and dropping the items, similar to Multiply's Photo Section ## Deliverables Please see the attached screenshots for more details of the project: [login to view URL] = 1st item is highlighted red and 2nd item is highlighted green [login to view URL] = 1st item is dragged to another location [login to view URL] = 2nd item moves up and the 1st gets placed on the new position
