The custom.css file mentions:

/* If customizing the photo dimensions, one
more value needs to change in the Individual
Photo template (t_photo.php). Search for the
following tag:

and change the value to your new photo MaxWidth.

WHERE IS THE t_photo.php FILE!

It's Driving me Mad ;)

Note that the stopdesign theme is originally an adaption of a - I believe - Wordpress theme. Probably not all css comments have been modified. The equivalent would be the image.php file. All info about Zenphoto themes in general are found on our theming tutorial (although the stopdesign is a more complex theme).

I found out that several CSS parmeters are set, but not put into action on the final page. It's really driving one mad.
