change banner img using media gallery

gistfile1.aw

<a href="media-upload.php?type=image&TB_iframe=true" class="thickbox" title="Select A Banner Image From Gallery" onclick="return false;" class="thickbox">
<img id="banner_image" src="<?php echo(htmlentities($banner_image)); ?>" width="450" height="25" />
</a>
<input type="hidden" id="banner_image_input" name="banner_image" value="<?php echo(htmlentities($banner_image)); ?>" />

<?php
/*
strip out everything but the image source and updates the form. First, the function eliminates all of the text returned except the image source. It then updates the banner image and the hidden input value that I am using in my form:
*/
function send_to_editor(html) {
    var source = html.match(/src=\".*\" alt/);
    source = source[0].replace(/^src=\"/, "").replace(/" alt$/, "");
    $("#banner_image").attr('src', source);
    $('#banner_image_input").attr('value', source);
    tb_remove();
}
?>

this is not as smart as re-attach plugin
