Uses of Photo Tools in Personal or Professional Life

I forgot in my last post to answer how I could use Flickr in my personal or professional life. Personally, I could share photos with my friends. Also, I belong to a Catholic group called Credo, and we could put all of our photos of our events in one album for everybody to see. Professionally, I wonder if we could use Picasa to show our photos of our exhibits. Right now, I directly paste them into the website. I would choose Picasa, because my colleague who takes the digital photos, uses Picasa all the time in her side jewelry business. I'd have to play with it to see if I could make it work.
