It looks like your gallery currently uses a version of SimpleViewer-Pro prior to Universal Playback being introduced in v2.1.0.
Your web page currently embeds a SWF file using SWFObject. This is a Flash file and there is no fallback mechanism for mobile devices or browsers which do not have Adobe Flash Player installed and enabled.
When SimpleViewer-Pro introduced the Universal Playback and the Mobile Player, in order to display the gallery images on non-Flash enabled devices and browsers, the SWF file was replaced with a collection of resource files (stored in the 'svcore' folder) and the embedding code changed.
In order for your gallery to be displayed on mobile devices, you will need to download the latest version of SimpleViewer-Pro (v2.3.1), upgrade your existing gallery and change the embedding code on your web page.
Instructions for downloading the latest version of SimpleViewer-Pro and upgrading existing galleries can be found here.
The current recommended embedding code can be found here.
