Viewing photos

I recently got new computer Vista 64. When I go to view my photos in
"Pictures" on the view menu my computer does not say "filmstrip". How do I
get to it so I can see my photos. I tried using the "extra large icons" but
this doesn't give me the large enough image for me to see and determine the
quality of my photos.
Also when I download from camera all my shots are correctly displayed. The
vertical shots are vertical where when after I put them in a windows folder
the verticals are all horizontal. When you are taking 200- 600 shots a day
it is impossible to go thru and rotate all of these.
Neither of these problems occurred in XP. Same camera. etc.
