    Default Photos don't show completely in mouseover script

    Hello all,

    I have a javascript that when you move your mouse over a thumbnail, a popup with a bigger photo appears. Now when a photo is bigger than half the screensize (eg. screenwidth = 1024 and photo is 600) the photo doesn't show completely anymore.
    Question: Is it possible to add something to the script so when the photo doesn't show completely anymore, the popup resizes to a smaller size that fits in the screen?
    Here's the code
    Code:
    <html>
    <head>
    
    <!--SHOW IN SCREEN 1024x768-->
    <script language="JavaScript"><!--
    self.moveTo(0,0)
    self.resizeTo('1024','768')
    //--></script>
    
    <script language="javascript" type="text/javascript">
    <!--

    Nevermind, I found a newer version of the script online.
