Crush your ipod to pieces
All you have to do is click on the iPod icon in your iTunes (when you connect your iPod to your computer), then you go to where it says Photos. Then you'll see a check mark in sync all photos. All you have to do then is click on the checkmark and then press Apply at the bottom right hand corner.
Hold the middle button then scroll down and click delete
Plug in you ipod and then a screen should pop up, after that you select photo and you can delete them from there. I'm glad to help!
Plug in your I iPod and a screen should pop up, then you click "open folder to veiw files", and last after that you right click the folder that says photos and scroll down to delete which then should delete the photos.
