ok, there pretty easy to do and I like them more than the script lissa has.
Images:
<a href="#" onclick="window.open('yoururlhere.html', 'Sample', 'toolbar=no,location=no,directories=no,status=no,m enubar=no,scrollbars=no,resizable=no,copyhistory=y es,width=500,height=500')"><img src="imageaddress.gif"></a>

To customise them, you see where it says toolbar=no, that means no toolbar and if you want the toolbar, change no to yes. Its like that with all the other parts like that too except the width and height part. You can change the width and height by changing width=500 to something like width=111 and height=500 to something like height=111

If you need anymore help, private message me.

there's another way to do images by going <input type="image" src="imageaddress.gif" ONCLICK="window.open('yoururlhere.html', 'Sample', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=yes, width=500, height=500')">
