checking existence of an element?

[The Plankmeister]

Is it possible to check for the existence of an element? I have a dynamic
page which may or may not have a <div> holding a bunch of thumbnails, and I
want a function to check for the existence of the <div>. Doing:

blah = getElementById( "thumbnails ");

Generates an error.... I was hoping it would just return false or
something... Is there a way of doing this?

Probably because it's
var blah = document.getEle mentById("thumb nails");

Using document.getEle mentById should return "null" if the element
isn't there. Which browser are you using?
