Import digital photos via USB?

[Palooka]

I'm running GNOME on Fedora 11. My daughter is shortly due to take possession of a digital SLR camera - a Canon EOS 400D. Apparently it comes with a USB cable.

I know very little of photography, or of image stuff on Linux, so I have a few questions:

Will I be able to connect it to my Linux box and import the images?

Is gthumb-importer the appropriate application for this? Is there better?

Are the images jpegs, or something else?

I only need to copy the images to the laptop and to be able to view them - I don't need to edit them or any such.

Thanks,
Palooka
