Everybody!

First, i have a file iframe_page.php using file_get_contents to display content from another page.

<?php
     $URL = "http://www.funnywow.com/index.php";
     $domain = file_get_contents($URL);
     $domain = preg_replace('/<head>/i', "<head>\n<base href='$URL'>\n", $domain);
     echo $domain;
?>

Next, i have a file index.php containing:

<!DOCTYPE html>
<html xmlns:fb="http://ogp.me/ns/fb#" lang="en">
    <head>
        <script>
    function HideDiv()
    {
        var x=document.getElementById("myframe");
        var y=(x.contentWindow || x.contentDocument);
        if (y.document)y=y.document;
        y.getElementById('MainPageBody').style.display="none";
    }
    </script>
    </head>
    <body>
        <iframe id="myframe" src="http://abc.myhost.com/iframe_page.php" width="800" height="600"></iframe>
        <br /><br />
        <input type="button" onclick="HideDiv()" value="Hide div MainPageBody" style="position:absolute" />
    </body>
</html>

Yes, i can hide <div id="MainPageBody"> inside the iframe, but I went for "choose an effect and upload photo" and "Go! view the final result", and the javascript is not working.
I want to test code in javascript that gets the src of the final image inside the iframe.

How can I do this?

Thank you very much.
