I have three digital cameras. Does every computer need drivers for these cameras or does the drivers come with their photo album?

Can I use one photo program to use all three cameras?

How would I get the drivers for each camera on the computer without their photo programs so that the photo program can import the images from the camera?

My Canon Zoom browser only sees my Canon camera. My Nikon Picture Project only sees my Nikon.

Don't want all these programs to use with separate programs.

Don't even like photo programs.
