+Instagrim  is an example web app using Cassandra as a back end.   The app allows picture uploads, creates a thumbnail and 
+a  B/W version of the picture, and a simple login.
+
+See Keyspaces.java for a definition of the keyspaces.
+CassandraHosts manages the connections. 
+The code uses org.imgscalr.Scalr for image manipulation
+It is a Netbeans maven based project.
+
+
+The code is used as an example for AC32007, School of Computing, Univeristy of Dundee.
+
+It implements the following URL patterns:
+
+/Image/*
+/Images
+/Thumb/*
+ /Images/*
+/Login
+/Register
+
+Not all work 100% correctly .  Some parts of the implementation are missing.
+
+Students are exected  to:
+1: Understand the code
+2: Fix any bugs
+3: Add functionality
+
+Some ideas for added functionality you might like to add (not all are simple, you decide what are and which you’d like to try).
+
+1: Extend the registration process and display a profile for users (add “\profile\*” for  instance)
+2: Upload a users picture to the users profile
+3: Add image filters.  So /alter/filername/* would create a new version of the picture with that filter  applied.  
+4: Allow users to comment on other users pictures. /Image/Comments/* would display the picture with the comments.
+
+This is not a limit to what you could do, use your imagination !
