Maybe you are not sure what a document is?  It's the full HTML (often
called a page) along with the script that is going wrong.  That's often
part of the document, but if it isn't you'd have to provide that as
well.

No, you really have to provide an example document along with the code
that doesn't work.

This isn't an example document.  One trouble with being a beginner is
that you may not know where the problem is, which is why a complete
self-contained example is so important.

Without one, all I can do is guess -- maybe there are no img elements in
this.parentNode?  Maybe 'this' is bound to the wrong type of object?
How many guesses do you want people to make before you simply provide a
document (and code) that exhibits the problem?

Just to be clear, I've cut and pasted your lines into a minimal document
and it does what I think you want.  The problem (whatever it is) is
elsewhere.

One thing is sure: if aDescendants is an element (as seems likely, but
without a full example that's just a guess) the calls to
getElementsByName and to getElementByID won't work.  These are methods
that are part of the document interface, not the element interface.
