Yes, normally I use the object the line of code is contained it.

class MyBusinessObject {

   void someMethod() {
     Image img ImageIO.read( getClass().getResource( "whatever.jpg" ));
     // etc...
   }
}

You can also use a constant.  MyBusinessObject.class.getResource(...) 
instead of getClass().

You can also use 
Thread.currentThread().getContextClassLoader().getResource(...), but 
that's usually only useful in situations where thread contexts are used, 
i.e. web apps.
