Thanks!
Milto, the site-owner, is a professional photographer and model-builder, and he also does a lot with 3D-programms.
I wished, some more of my clients have that professional photos...
My job only was to prepare a structure, which is easy to handle and show the photos best.
The detail pages are made with "Topics" (a new version, not public yet). with this version one can include another module, in this case the SmoothGallery.
The pages like "Making of" or "Eggs in action" I have made with Members + Fancybox. it seems that Fancybox doesnt work, when there is SmoothGallery on the same page.

I'll have a look on that.
