[thelist] hiding a password in a simple javascript prompt box

There are a bunch of ways to do this. One of the ideas I've played with is
using JavaScript to load an image like:

var myimg = new Image();
myimg.src = password + ".gif";

and then checking the byte size of the image. If the image does not exist,
it will have no byte size (IE reports it as -1 if you view properties). So,
to change the password, you'd just rename that image. I haven't figured out
how to check the size of the image using the DOM and JS (i've only played
with this idea on the server-side), but hopefully this will get you on the
right path.
