Nextgen slideshow won't load (spinning star)

My imagerotator Sildeshow shows only spinning star … I search the entire Forum, find many post but no solution.

Link: https://www.michaelbihn.de
There is e extra page “sildeshow” for these tests.

Die Path to the .swf is correct (an it load) but then die Sildeshow doesn’t load the picktures.

What a already have checked:
– <?php wp_head(); ?> is includes
– Path to .swf is correct
– try using the old imagerotator.swf (without logo)
– XMl-Path is correct

I wonder a little bit about

JS-Code:

<div class="swfobject" id="so44_1" style="width:320px; height:240px;">

</div></div>
<script type="text/javascript" defer="defer">

	params : {
		wmode : "opaque",
		allowfullscreen : "true",
		bgcolor : "#000000"},
	flashvars : {
		file : "http%3A%2F%2Fwww.michaelbihn.de%2Findex.php%3Fcallback%3Dimagerotator%26gid%3D44",
