Adding upload/insert photo media function to plugin

Hi I’m trying to add the upload/insert photo media function to a plugin that currently doesn’t support or include it. (shopp in the product edit pages)

I had it working by viewing source and coping the code for the <script></script> javascript and the div id=”media-buttons” class=”hide-if-no-js”> code.

This method was working, but not working now I think it has to do with the page id’s or something. The zoom box won’t come up when I click the icons anymore.

Any cleaner and working methods of adding that feature to pages that don’t have it?

<script type="text/javascript">
//<![CDATA[
addLoadEvent = function(func){if(typeof jQuery!="undefined")jQuery(document).ready(func);else if(typeof wpOnload!='function'){wpOnload=func;}else{var oldonload=wpOnload;wpOnload=function(){oldonload();func();}}};
var userSettings = {'url':'/hadpress/','uid':'1','time':'1267931133'};
var ajaxurl = 'http://hosting-and-designs.com/hadpress/wp-admin/admin-ajax.php', pagenow = 'post', adminpage = 'post-php',  thousandsSeparator = ',', decimalPoint = '.';
//]]>
</script>

<div id="media-buttons" class="hide-if-no-js">
Upload/Insert
	<a href="media-upload.php?post_id=3&type=image&TB_iframe=true" id="add_image" class="thickbox" title='Add an Image' onclick="return false;"><img src='images/media-button-image.gif' alt='Add an Image' /></a>

	<a href="media-upload.php?post_id=3&type=video&TB_iframe=true" id="add_video" class="thickbox" title='Add Video' onclick="return false;"><img src='images/media-button-video.gif' alt='Add Video' /></a>
	<a href="media-upload.php?post_id=3&type=audio&TB_iframe=true" id="add_audio" class="thickbox" title='Add Audio' onclick="return false;"><img src='images/media-button-music.gif' alt='Add Audio' /></a>
	<a href="media-upload.php?post_id=3&TB_iframe=true" id="add_media" class="thickbox" title='Add Media' onclick="return false;"><img src='images/media-button-other.gif' alt='Add Media' /></a>
