You want to get a img from a div (and sometimes you say "find a
descendent of a certain element" which is even more vague).  Given that
specification I know you have the right method to call (though with the
more vague one, the firstChild property might be enough), but something
is not right because you want to "figure out why I can't get it to
work".

I did: an example document with the code that does not work.

Yes, you've make a mistake somewhere.  If you'd like some help to find
out where, given an example document, state the element you'd like to
find and show the code that doesn't work.

You even quoted me asking:
