The way i validated files in ZF2

in composer.json

  "imagine/Imagine": "0.3.*",

in your controller

use Zend\Validatior\File\Size;
use Imagine\Gd\Imagine;
use Imagine\Image\Box;
use Imagine\Image\Point;

public function imageAction()
    {

        $id = ( int ) $this->params ()->fromRoute ( 'id', 0 );
        if (! $id) {
            return $this->redirect ()->toRoute ( 'newscategory' );
        }

        $form = new YourForm();
        $form->get ( 'link_id' )->setAttribute ( 'value', $id );
        $request = $this->getRequest();
        if ($request->isPost()) {
            // Make certain to merge the files info!
            $image = new Entityimage();
            $form->setInputFilter($image->getInputFilter());
            $post = array_merge_recursive(
                    $request->getPost()->toArray(),
                    $request->getFiles()->toArray()
            );

            $form->setData($post);

            if ($form->isValid()) {

                $size = new \Zend\Validator\File\ImageSize(array(

                        'maxWidth' => 1024, 'maxHeight' => 920,
                )); //minimum bytes filesize
                $isImage = new \Zend\Validator\File\IsImage();
                $mimeType = new \Zend\Validator\File\MimeType(array('image/gif', 'image/jpg','image/jpeg','image/png','enableHeaderCheck' => true));
