Hell everyone - this has had me pulling my hair out all day!

I'm using the latest version of Zen and have been making some decent progress getting my site re-designed from a static html site over to a new all singing/dancing database driven site.

Anyhow - i am trying to center the main product image in the product detail page.
Here's the link: http://richtonemusic.co.uk/store/ind...&products_id=1

As you can see it is currently aligned to the left....and i can't get it to budge...Gggrrrr

I've tried altering the stylesheet, and entering info straight into tpl_product_info_display.php

Can someone please give me a work around on this so I can spend the rest of the evening with my girlfriend!!??

Thanks in anticipation.
