I've done a bit of searching and haven't found anything related to using a spherical viewer with zenphoto. There are a few open source viewers out there, but I was wondering if there was an extension that supported rectilinear viewing integrated with zenphoto? Failing that, are there any recommendations on how this might be done? It's been a while since I've poked at all in zenphoto, but this might be a good reason to get back onto the playing field..
Thanks for any suggestions!
