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 !
