in controller, you don’t set any header! in view you do set. like following :

View.php —>>


header("Content-type: ".$model->image_type);

echo $model->image_data;

in controller, only first line is enough. which loads data from the db. that’s it.

Controller.php—>>actionView()




$this->renderPartial(

  'view',

  array(

    'model'=>$this->loadModel(),

  ),

  false,false

);

and loadModel would be

Controller.php—>loadModel()


public function loadModel()

	{

		if($this->_model===null)

		{

			if(isset($_GET['id']))

				$this->_model=Image::model()->findbyPk($_GET['id']);

			if($this->_model===null)

				throw new CHttpException(404,'The requested page does not exist.');

		}

		return $this->_model;

	}

Try and let me know.

There is a similar topic here in the forum with the same problem.

Read it and follow the instructions to debug the error.

@mods maybe it would be good to merge the topics together
