how to center the simpleviewer gallery...
If you are trying to center your gallery vertically between your header and footer, then using the Vertical Resizable Gallery with Header Example sample as a template may be the best course of action.
If you are trying to center your gallery horizontally, then using the following code should work:
<div id="sv-container" style="margin: 0 auto;"></div>
However, this will center the gallery only within its most immediate parent container, which, itself may need centered within its own parent container.
Hmmm...it seems this is an issue in IE but my Firefox is responding well to the code
Your web page has no Doctype Declaration so, without knowing which set of standards your web page should be conforming to, Internet Explorer could be displaying your web page with unpredictable results.
Looking at the code on your web page, it would appear that the most appropriate Doctype Declaration would be HTML 4.01 Transitional.
Put the following code at the very top of your web page (before the opening <html> tag):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
... and then check your web page for errors with the W3C Markup Validation Service and fix any errors reported.
Once your web page's code validates correctly, your web page should be displayed with greater predictability and consistency across different browsers.
