I got my first digital camera back in the 80's and have been using them ever since. For good fotos of your work to be posted to a website you need about 3 MP. You can go beyond that and as you do the pics get larger. What you want to be able to do is take a pic, post it as a thumbnail about 2" x 2" or less and be able to click on it to expand to about 5x7 or 8x10 if you want. 3-5 Mega Pixels will work fine. Lots of good cameras at a fair price point.

I use a Nokia cell fone with a camera built in. It gives me 5 MP and has lots of features that most cameras have. It also keeps me from hauling around a camera and a fone.
