I have a site developed and need to add a new functionality to it. Here's what needs to be done:
I have an image of a christmas tree and that needs to be decorated using some christmas decorations as per the users will. There's a basket of decorations that will be used for it. The registered users will be able to drag a decoration from the basket and drop it on the christmas tree. After decorating the tree, the user can save it to the database. On his next login, he should be able to view the tree as he decorated it and make changes to it if desired.
The site is developed in .net and the database used is SQL Server.
