After I read the instructions, they are both different, I have entered in Muse follwing HTML code.
<!--START JUICEBOX EMBED-->
<script src="http://kombo.de/muse-gallery/gallery2015/jbcore/juicebox.js"></script>
<script>
new juicebox({
containerId : 'juicebox-container',
baseUrl : #http://www.kombo.de/muse-gallery/gallery2015/',
galleryWidth : '100%',
galleryHeight : '600',
backgroundColor: '#222222'
});
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->
But nothing appears on the site!
The gallery folder is "gallery2015" named.
wwww.kombo.de/muse-gallery
The code made after the instructions of MuseThemes - he ist differnt to yours!!!!!
Now it works. Have taken the HTML-Code your wrote.
