Javascript и работа с Media Library на WordPress

В примера по-долу извиквам Media Library на WordPress, чрез натискане на картинка.

<script>

function getmedia(ident){
	
    // Instantiates the variable that holds the media library frame.
    var meta_image_frame;

    // Runs when the image button is clicked.
	
    j(function(){

        // Prevents the default action from occuring.
      //  e.preventDefault();

        // If the frame already exists, re-open it.
        if ( meta_image_frame ) {
            meta_image_frame.open();
            return;
        }

        // Sets up the media library frame
        meta_image_frame = wp.media.frames.meta_image_frame = wp.media({
          //  title: meta_image.title,
         //   button: { text:  meta_image.button },
            library: { type: 'image' }
        });

        // Runs when an image is selected.
        meta_image_frame.on('select', function(){

          //  return false;

            // Grabs the attachment selection and creates a JSON representation of the model.
            var media_attachment = meta_image_frame.state().get('selection').first().toJSON();

            // Sends the attachment URL to our custom image input field.
			
					
	document.getElementById("imgc_"+ident).src = media_attachment.sizes.thumbnail.url;
			
        //media_attachment.id; 	имате и id-то на самият attachment (за повече опции, проверете в WordPress документацията)

			
        });

        // Opens the media library frame.
        meta_image_frame.open();
    });

	 
	 
	 
}

  </script>

Ето това са картинките, чрез които ще извикваме Media Library и ще заменяме src адреса.
