Galleria Fatal error: Could not extract a stage height from the CSS. Traced height: 0px

Make sure you include:

Head:

<link type="text/css" rel="stylesheet" href="https://stackoverflow.com/questions/6610522/galleria/themes/classic/galleria.classic.css">
<script type="text/javascript" src="js/galleria-1.2.5.min.js"></script>
<script type="text/javascript" src="galleria/themes/classic/galleria.classic.min.js"></script>

Also the in page style:

#galleria{height:467px}

And below the images:

<script type="text/javascript">
$('#gallery').galleria({
width: 700,
height: 467 //--I made heights match
});
</script>

If you have problems with this troubleshoot with a clean installation and add until you find the cause.
