*I have to find out how to delete the photos from my ipod.*
Remove the photo from the folder that you linked to when you set the preference "synchronize photos from" and update the iPod. For example, if the iPod is getting the pictures from the folder "My Pictures," remove or delete them from My Pictures and sync your iPod.
Here's a simple "How To" on downloading and managing photos from a folder on your hard disk to an iPod:
1 Create a folder on your hard drive to hold the photos you want on your iPod. Call it iPod Photos for example
2 Drag the photos you want from your usual picture folder into the folder you just created
2 Open iTunes, select your iPod in the iTunes Source list.
3 Click the Photos tab and select “Synch photos from.”
4 Choose “Choose Folder” from the pop-up menu and select the iPod photos folder you created.
5 When you want to change what photos are on the iPod just add or remove the photos from the folder you have made and syncronise the the iPod
