For those who are unable to integrate Imagine properly like me..

I found another solution WebinoImageThumb here which worked perfectly fine with me. Here is little explanation if you don't want to read full documentation :

Run: php composer.phar require webino/webino-image-thumb:dev-develop and add WebinoImageThumb as active module in config/application.config.php which further looks like :

 array(
        'Application',
        'WebinoImageThumb'
    ),

.. below remains the same

Now in your controller action use this through service locator like below :

// at top on your controller
use Zend\Validator\File\Size;
use Zend\Validator\File\ImageSize;
use Zend\Validator\File\IsImage;
use Zend\Http\Request

    // in action
$file = $request->getFiles();
$fileAdapter = new \Zend\File\Transfer\Adapter\Http();
$imageValidator = new IsImage();
if ($imageValidator->isValid($file['file_url']['tmp_name'])) {
    $fileParts = explode('.', $file['file_url']['name']);
    $filter = new \Zend\Filter\File\Rename(array(
               "target" => "file/path/to/image." . $fileParts[1],
               "randomize" => true,
              ));

    try {
         $filePath = $filter->filter($file['file_url'])['tmp_name'];
         $thumbnailer = $this->getServiceLocator()
                        ->get('WebinoImageThumb');
         $thumb = $thumbnailer->create($filePath, $options = [], $plugins = []);
         $thumb->adaptiveResize(540, 340)->save($filePath);

      } catch (\Exception $e) {
          return new ViewModel(array('form' => $form, 
                     'file_errors' => array($e->getMessage())));
      }
  } else {
      return new ViewModel(array('form' => $form, 
                 'file_errors' => $imageValidator->getMessages()));
  }

Good luck..!!
