That's why I don't recommend reducing a camera's resolution. For the most part, you should always shoot at your camera's highest pixel resolution.
Here's my question:

Do higher resoution pictures take up more space on the computer (are they larger files)?

I do not want to use a 2nd photo program unless absolutely necessary. Currently I plug my camera into my computer (via USB), and I can upload pictures to My Pictures (Windows XP). The files are about 1MB (w/ 3.2MP camera). I would like to get 5MP or more, but I don't want files that are 2MB+. I know that I can reduce size when I send in Outlook, and the resulting files are 30-40kb. However they don't look nearly as good.

What is the default size file for pictures taken with higher resolution?

Can people that are using larger MP cameras "maxed out" please provide insight?

Also, where should I turn for trustworthy reviews? CNET?

Thanks,

Sam
