polaroid digital camera

i am having trouble with my polaroid pdc 2070 digital
camera.the problem is that when i rig up the camera to the
computer it works ok but when i need to take pictures from
the camera to put on the hard drive i have to flick the
switch to playback which in turn shows the camera as drive
E:
i double click the drive and folders containing the
pictures but when i double click on a picture , the
computer freezes for long periods of time unless i close
the program down in task manager

can anyone tell me how i get the pictures off the camera?

thanks in advance
