Your gallery displays and functions OK when I view it on an iPod Touch and also in desktop browsers (both with and without Adobe Flash Player enabled) so it should also display and function OK on an iPad.
Try clearing your browser's cache before reloading your gallery to ensure that your browser fetches and uses the most recent gallery files from your web server.
Also, try viewing the gallery on its own web page (rather than embedded in your 'Sfigure.html' web page) to see if this displays OK: http://www.twolambs.ca/SandisGallery/Fi … gures.html
Also, please make sure that you are trying to view your gallery over a wi-fi connection.
If you are using a 3G connection, please see this FAQ:
Why can't I view my gallery on a 3G mobile connection?
Incidentally, I notice that your 'Sfigure.html' web page does not use a Doctype Declaration (DTD). Please see here for details.
All web pages should use a DTD so that the user's browser knows what set of standards the code on your page conform to.
Looking at the code on your page, the most suitable DTD would appear to be HTML 4.01 Transitional.
Place the following code at the top of your 'Sfigure.html' web page (before the opening <html> tag).
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
