<script type="text/javascript">
 
$.noConflict();
function adjustIframes()

  $('iframe').each(function(){
    var
    $this       = $(this),
    proportion  = $this.data( 'proportion' ),
    w           = $this.attr('width'),
    actual_w    = $this.width();

        proportion = $this.attr('height') / w;
        $this.data( 'proportion', proportion );

    {
        var h =  Math.round( actual_w * proportion );
 
        if (!isNaN(h)) {
            if (console && console.log) console.log("Resizing iframe to height: " + h);
            $this.css( 'height', h + 'px' );
 
            if ($this.get(0).contentWindow.postMessage) {
