title: image resize zf2
body: <p>I need to implement image resize functionality (preferably with gd2 library extension) in zend framework 2. </p>
  
  <p>I could not find any component/helper for the same. Any references?</p>
  
  <p>If i want to create one, where should I add it. In older Zend framework, there was a concept of Action Helper, what about Zend framework 2 ?</p>
  
  <p>Please suggest the best solution here.</p>
