Please elaborate on your request. If I understand you correctly, when you open the image dialog for editing, you want to be able to add multiple images on the dialog. If this is right then you need to start with understanding how the SmartImage works (see ). Also, read this online doc  on how to deal with widgets. Note that an image xtype is html5smartimage.
