Yes, you should call ArtMaker.makeArt( ... ), but you do need to have the right parameters.
The trick is that you need to figure out all of the right actual parameters to give it. You *DON'T* pass in the names of the formal parameters.
And for BatchArtMaker, the user didn't provide a full filename for you. You need to create your own filename (which is a String) to be "images/bird3.jpg", then "images/bird4.jpg", etc... and pass that in to the method.
