Yep, it's possible, almost any digital camera can work under linux, there are some good programs that can be used to download pictures from your camera to the pc, all depends on what you want
- If you want to use only the command line you can use
gphoto2 or
ptpcam
- If you want to use a gui i recomend you
gtkam (under gnome or xfce) but if you use KDE then maybe you would prefer
digiKam
there might be another options, those are the ones i know and i tell you this programs works just fine
