In order to add objects, you must manually write the code into your world's constructor. We can not create new objects ourselves when the file is uploaded to greenfoot gallery.
For example, in the constructor class in the world, use the method addObject to add a new object in.
If you're not sure how to do this, have a look at http://greenfoot.org/greenroom/images/1/12/Adding_objects.pdf and it'll walk you through the process.
