Thank you Jules! I thought that *might* be the case, but seeing the
tell-tail jQuery code in the DHTML was a little confusing to me. But
yes, I think I understand it now. "alt" is a normal JavaScript object,
NOT jQuery. So when accessing JS objects I must always use the [0].
This also seems to apply when initializing a variable, as in
var myVariable = $("#myElement")[0];
Thanks again!
