If I uses the FTP to transfer photos to the appleTVs harddrive, how can I see the them without using XBMC or Boxee??
The only way for photos to show up in the Photos menu option is to use iPhoto or Aperture on the Mac or Photoshop Album or Photoshop Elements on the PC. The Apple TV will not look for pictures in any other place nor will it go off of anything but the XML file iTunes puts on there. XBMC/Boxee are the only tools to see pictures on the Apple TV other than that.
