I just bought an iPod nano, which I immediately set to sync up the images from several folders, it also includes the full resolution ones (incase i want to edit them on another machine). However I haven't found an easy way to add photos and have them show on the screen. If I add the folders under itunes > preferences > ipod it deletes the folders i set in the first place. I'd really like to just add more pictures, and be able to preview them on my ipod as well.
How can I do this? If it can't be done is there any 3rd part application you can recommend?
