Hello,
Yes, we will definately want to add digital photos to Pluto, and in fact, our commercial media directors will all have card readers for that. Our focus at the moment is streamlining the installation process, and getting all the media to work 100% stable. So, we're holding off on new modules until we're sure the ones we've already released are working for everybody. Our online documentation has programmer's guides, though, that explain the process.
