With Cluster we could create a place where the students can post photos easily and at same moment as they capture them by their phones. 

It can be used from phone, iPhone, tablet and computer and keep photos private, shared only with a chosen friends. It can be found on Interenet and in Market (Application Store) for Androids. 
We can make different galleries depending on themes or our cities. We can also vote for those that we like by giving them "hearts".
