What type of camera? Depends what you want to take pictures of. If all you want it for is so you can post pictures when needed
then there are lots of inexpensive cameras out there. If you also want to be able to take a nice portrait shot of someone than you will need a better camera.

They range in price from $100 to $10,000 or more. I lot of phones take great pics with good lighting.

If you have one of the better phones on the market just use it with so good lighting.

I use photobucket (www.photobucket.com) to upload my pictures so I can post them. It quick, easy and FREE.

Hope this helps...
