Looks to me like you have the paths to your jQuery, lightbox js, img and css files incorrect. They're pointing to crawfordcountyhistoricalsociety.org/Pages/
, while it looks like they're actually located at crawfordcountyhistoricalsociety.org/
. Try changing your import lines in the page source from:
<script src="js/jquery-1.10.2.min.js"></script>
<script src="js/lightbox-2.6.min.js"></script>
<link href="css/lightbox.css" rel="stylesheet" />
To:
<script src="/js/jquery-1.10.2.min.js"></script>
<script src="/js/lightbox-2.6.min.js"></script>
<link href="/css/lightbox.css" rel="stylesheet" />
(In other words add a leading slash to indicate they're at the root of your folder structure)
