Vanilla 2

Hi all, I just integrated prettyPhoto into a test page on my compute. It displays the gallery just fine, but it won't show the control buttons (play, pause, next, previous, close). The controls are there (when I click they work) but they're not being displayed.

I've put the theme files where they should be relative to my page. It's the same for every theme file so it's not a theme problem. I'm using the CSS that came with the download, unaltered.

It works fine on the demo page that came with the download, so I'm stuck. What could I be doing wrong?
