Can I view photos on my iPod photo/"Color"? nano?
Depending on the model, to view photos on your iPod photo/"Color", you either need to import photographs using Apple's iPod Camera Connector, or transfer images from your computer through iTunes 4.7 or higher to the iPod.
For the current iPod U2 Special Edition "Color", iPod "Color" (20.0 GB), the version of the iPod photo (60 GB) introduced on February 23, 2005 and renamed iPod "Color" (60 GB) on June 28, 2005, as well as the discontinued iPod photo (30 GB), the simplest way to transfer photos from many digital cameras to your iPod is to purchase and use Apple's iPod Camera Connector (US$29). This device simply allows you to directly connect a digital camera to the camera connector and in turn connect the camera connector to the iPod "dock" port. Photos imported using the iPod Camera Connector are immediately viewable, with the exception of RAW format images and video clips. However, photos imported using the iPod Camera Connector cannot be immediately viewed as a slideshow with transitions.
On versions of the iPod photo (40 GB, 60 GB) released prior to February 23, 2005, photos transferred directly from a digital camera using an iPod-compatible media reader are not immediately viewable, but photos transferred through iTunes 4.7 or higher, which converts photos into a "thumbnail" format, can be viewed on the iPod photo itself or displayed using the iPod photo connected to a TV or projector.
The iPod nano, introduced September 7, 2005, can display photographs on the internal display "loaded" from a computer, but as it lacks video out, it cannot display photographs on a television or projector. The iPod nano also does not support the iPod Camera Connector or third-party solutions, so photos cannot be transferred from a camera.
