How to Resize an Image Picture on a Mac

Hi All
So I thought I would post up and easy guide on how to resize a picture on a Mac.
I want to try and spread out the Tutorials evenly so I will try and do one per day on each topic.
When sending emails with images via email, most free email servers like Yahoo or Google have a limit on how many images you can send at once. Usually it’s around 10 meg in size. To get around this you can resize your image to make them smaller so that you will be able to attach more images to the email.
Making the pictures smaller will also allow you to upload and download them faster and when adding images to a website will allow them to load faster in the viewers web browser.
Resizing a picture on a Mac is quick and painless when you know how to do it and it the software is already built into your Mac OS X. So you have no reason not to be able to this yourself.
