Sorry – didn’t realize that you had provided the credentials. I will try now.
There seems to be some sort of a conflict introduced either by your theme or a different plugin. It is preventing Photonic’s JavaScript code from being included in your page. That JS code runs after your images are loaded, to finally make them visible.
You will need to figure out where the conflict is arising – I don’t have familiarity with your theme or your plugins. It would seem like something at your end is deregistering standard libraries and including custom ones. E.g. I see that jQuery has been replaced by a non-standard (and very old) version, and that too with a different handle. WP by default bundles its own jQuery with the jquery handle, but whatever you are using seems to be deregistering the jquery handle and is adding the non-standard script with a jquery-js handle – this is guaranteed to break plugins that rely on the standard code.
