Hi Guys, soz and Gals

,
I am trying to alter the Detail Page image to approx 325px to create a better balance between text and image on a page width of 680px
However despite uploading an image @ 325x325 with '
Change size during upload' Unticked, the image is still displayed at 200x200 in the product view. I've tried several times, different browsers etc but no joy

If this doen't work, what exactly is the point of the tickbox?
I am more than happy with css code , and have amended several other page elements via this method but the 200px is in the HTML Code (style element), not set by css.

Is there any way I can change it or am I doing something wrong with my uploading?

Thanks in desperation
Nigel
