Hi,
Front Row is a nice app, but without support for pictures. I mean: for those like me without Aperture or iPhoto.
I read that Front Row uses metadata tags to display photos. So the solution could be to add some metadata to each of the photos or folders which contain image files.
Unfortunately, i’m absolute unsure how the tag-structure to add might look like and so. I ask the community and users who have possibility to play around with iphoto/aperture pictures if applying a certain metadata via Applescript is possible so that they show up in Front Row.
