Magento - How to allow certain tags (iframe, embed) in Magento's CMS editor?

To overcome the limitation of Admin Editor in Magento, try this:
Look in this file:
js/mage/adminhtml/wysiwyg/tiny_mce/setup.js Find this block of code:

var settings = {
        mode : (mode != undefined ? mode : 'none'),
        elements : this.id,
        theme : 'advanced',
        plugins : plugins,
        theme_advanced_buttons1 : magentoPlugins + 'magentowidget,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect',
        theme_advanced_buttons2 : 'cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,forecolor,backcolor',
        theme_advanced_buttons3 : 'tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,iespell,media,advhr,|,ltr,rtl,|,fullscreen',
        theme_advanced_buttons4 : 'insertlayer,moveforward,movebackward,absolute,|,styleprops,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,pagebreak',
        theme_advanced_toolbar_location : 'top',
        theme_advanced_toolbar_align : 'left',
        theme_advanced_statusbar_location : 'bottom',
        theme_advanced_resizing : true,

and add this after it:

extended_valid_elements : 'iframe[src|style|width|height|scrolling|marginwidth|marginheight|frameborder],style,script',

That's All.. Enjoy.. :)

To get all gallary images of a product, try this code:

<?php $_images = Mage::getModel('catalog/product')->load($_product->getId())->getMediaGalleryImages();?>
<?php if($_images) {  ?>
    <?php $i=0;
              foreach($_images as $_image) {  $i++;?>
              <a href="#">
              <img src="<?=$this->helper('catalog/image')->init($_product, 'thumbnail',$_image->getFile())->resize(200, 130); ?>" width="200" height="130" alt="<?=$this->htmlEscape($_image->getLabel());?>" title="<?=$this->htmlEscape($_image->getLabel()); ?>" />
