Web Cam Does it work for you on your Computer?

I finally could somehow maneuver the computer (netbook) and push the take button on web cam and get a picture of Little Killer my cat who is about 20 years old.  Then I did videos which are absolutely terrible.  I guess it takes some practice as I got seasick watching it.   Overhead light made it look a little yellow, but it worked here for still photo.  I tried to e mail ny video to only family members but computer said my attachment was too big.  Sigh.
