I searched for photos on Shih Tzus since I am a proud owner of one, I am always interested in seeing other people's dogs. There sooooo cute! The only tag assigned to this photo was, "Report Abuse".
I thought Picasa was pretty cool. I can see it being used by students who may be looking for photos/images for assignments or for their powerpoint presentations.
I probably won't use Picasa since I can use Facebook for this purpose.
