JavaScript and how to turn it on!
JavaScript is a little bit of code which makes the popup images...well...popup!

It is turned on by default in most browsers, but if the popup images don't appear to be working, it is possible that someone has turned it off.

Switching it back on is very easy. Look down the following list to find the browser you are using (version numbers can usually be found by opening the program and clicking Help>'About Internet Explorer' or 'Netscape'), and then follow the relevant instructions. After that the popups should work!

Go to the View menu and select Options.
Click the Security tab.
In the Security dialog box, click the checkbox beside Run ActiveX scripts, near the bottom of the tab.

Go to the Tools menu and select Internet Options.
Click the Security tab.
In the Security dialog box, click on the globe for Internet zone.
