I been using the OSFLV player for a few months and recently upgrade for the new post-image functionality. I made a few custom modifications, changing the center button etc. Now I'm trying to set a post-image for one of my videos with the following code:

<object width='600' height='400' id='flvPlayer3'>
  <param name='allowFullScreen' value='true'>
  <param name='movie' value='{site_url}images/uploads/player.swf?movie={site_url}images/uploads/thevideo.flv&bgcolor=0xBABABA&fgcolor=0xFFFFFF&volume=&autorewind=on&clickurl=&clicktarget=&postimage={site_url}images/uploads/theimage.jpg'>
  <embed src='{site_url}images/uploads/player.swf?movie={site_url}images/uploads/thevideo.flv&bgcolor=0xBABABA&fgcolor=0xFFFFFF&volume=&autorewind=on&clickurl=&clicktarget=&postimage={site_url}images/uploads/theimage.jpg' width='600' height='400' allowFullScreen='true' type='application/x-shockwave-flash'>
 </object>

Where {site} is replaced in my CMS by the website prefix, which is essentially rendering the absolute URL to the browser. Anyway all the URLs are correct and the video plays fine but the post-image isn't being displayed. I had it working previously, but even when it was working it was breaking in IE7 and IE8. A blank box with scrollbars was being displayed. Am I missing something here?
