Thank you for your quick answer.

The embed code looks pretty good:
<!--START JUICEBOX EMBED-->
<script src="jbcore/juicebox.js"></script>
<script>
new juicebox({
containerId : "juicebox-container",
galleryWidth: "100%",
galleryHeight: "100%",
backgroundColor: "#222222"
});
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

The gallery folder is on my desktop (I'm not a developer btw, trying to figure this out)...

Thank you
