Importing photos from Kodak EasyShare camera

I am attempting to import photos from my Kodak EasyShare CX7300 camera into iPhoto. I have uploaded photos from this camera onto the computer before, but for some reason, I am no longer able to do so. I have checked the cord connections of both the USB port and the camera, and both are fine. When I plug the camera into the computer and turn the camera on, the green light on the camera flashes and iPhoto opens, but the import process does not begin. I have been unable to find a way through which I can manually import the photos into iPhoto. I cannot install the EasyShare software that came with the camera because of restrictions placed on the computer by my school. Any suggestions, other than a new camera or a better computer? :-D Like I said, I've imported photos from the same camera to the same computer... why isn't it working now?????
