Check in System Preferences/CD's & DVD's that you have "Open iPhoto" selected for "When you insert a picture CD".
Once photos are imported into iPhoto, you can safely delete them from your User/Pictures.
be careful impoting photos into iPhoto. iPhoto may ask if you want to delete the photos from the source. I always say NO.
