Help:My Photos Are Locked in My Digital Camera

I took some excellent photos of my classmates from the 1970s last night at the mixer and they are locked inside the hard drive of my digital camera.It is a Kodak Easy Share camera and I tried to release them by adding them with the power cord to my computer. No luck! I am going crazy! Any ideas!? They are not on the chip. I already emptied the pics we took today that my 19 year old daughter Who Girl  did. She released those photos and I will share tomorrow. I really am unhappy! :(
