You're treating that method as if it were a constructor. You need to treat it as a proper method. So:
Note that this is actually bad design. First of all, you need to create an object to call the method. The method should be static instead, unless you want it to be overridden.
Second,
you should never create methods with the same name as constructors / the class. It leads to confusion, and in your case to improper use of the method. I'd call the method
loadImage instead, as the method doesn't draw anything - it loads an image from a file.
