Cascading Drop-Down Menu?

[wxdqz]

I was looking at the code found at:

<!-- m --><a class="postlink" href="http://javascript.internet.com/navigation/cascade-menu.html">http://javascript.internet.com/navigati ... -menu.html</a><!-- m -->

My first question is, how do you alter the size of the cascading drop-down boxes?

My second question is, would images look smooth in the cascading drop-down boxes?

My third question is, what is the best way to do a cascading drop-down image menu?

Thanks.
