CSS conflict

Hi!

I have got a CSS conflict on my site that needs to be fixed.

www.quality4-u.com/Vacation-Ideas-Turkey-Travel-Guide-Pdf-eBook.html

Social share buttons don't work with
<script language="JavaScript" type="text/javascript" src="/~media/elements/PhotoGallery/js/prototype.js"></script>

This is the photo gallery. One option is its removal, I would need a more professional advice. :)

Best wishes,
Daniel
