The 3.0 firmware lets you sync different content with different computers. Music, Movies, TV Shows, Podcasts, Photos, Info, and Applications can each be synced with different computers if you wished. On a Windows system, you can sync photos through iTunes from Adobe Photoshop Elements versions 3.0-5.0, Adobe Photoshop Album 2.0 or later, or a folder from Windows Explorer, as documented by
this. If you have folders within the folder of choice you can sync more than one folder of photos. For example if you have selected to sync pictures from the My Pictures/Pictures folder, and you have folders within My Pictures, you will have the option to sync selected folders rather than the individual images in that directory. Hope this made things a little more clearer.
