This is described this in detail in 3: Sync Your IPod touch with iTunes. Receive as email attachments: While this is not useful for large numbers of pictures, it works well for one or a few photos. Check out 14: Email on your iPod touch for more details about how to save attachments. (Once saved, these images show up in the Camera Roll album.) Save images from the Web: Sometimes you ll see a great image on a web site. Press and hold it to see the pop-up menu and then select Save Image. (Like other saved images, these end up in the Camera Roll album.) Download images from within an app: A good example of this is the Wallpaper image shown in 7: Personalize and Secure your iPod touch.
