Hi
I want to have different thumbnail sizes for portrait and landcape images. From what I have observed this is not build into the current version of ZenPhoto. I imagine it could be possible and maybe someone already has a hack to do this or an idea on how to do this.

It would be cool if there was an option in the admin to set the image to a portrait/landscape thumbnail size.

Is it possible?

Bump this topic :-)

You have to do that on your theme using http://www.zenphoto.org/documentation/functions/_template-functions.php.html#functionisLandscape
