	{
		public static $db = array(
				'Type' => "Enum('Image,Embed','Image')",
				'Title' => 'Text',

@TODO

Bulk Editing Tools

• Create the rest of the Components...

Bulk Image Upload

• Add individual actions for each upload (update + cancel)
• Handle and display errors better for: creation, update, cancel
• Make it work not only for images -> might need to rename this component then? -> should be handled by another component
