Hyper link for images in CGRIDVIEW in YII

here the images residing in the uploads folder in the application folder itself 

where as the image name residing with the reg_no(primary key) so the $data->reg_no is appended with the image attribute

note that the value field should be defined in single quotes (' ')  only. in single quotes double quotes exists. dont define in double quotes

array(    
            'header' => 'Image',
            'name' => 'image',
            'value' => '($data->image === "NIL" ? $data->image :CHtml::link($data->image,Yii::app()->baseUrl."/uploads/".$data->reg_no."_".$data->image,array("target"=>"_blank")))',
            'type'=>'raw',
        ),


and display them in CGRIDVIEW:

Here the application name is dev_tslr where the images are residing outside of the application names tslrimgs

for example in the same D: the both directories dev_tslr and tslrimgs are existing

so the url Yii::app()->baseUrl gives us the path of dev_tslr since the tslrimgs are outside of this folder 
../ is appended so we move back to home folder i.e., outside of application folder and then we are choosing the tslrimgs

if the uploads folder existing in the application itself then we can directly use the path

Yii::app()->baseUrl.'/uploads/' can be used

Yii::app()->basePath -- gives the app_dir/protected path.
