Measuring Image Size Instructions

Note: For this tutorial you need to use Firefox as your browser and a free Firefox add-on application called Measureit. This is a very handy application which allows you to measure pixels on your screen. We highly recommend using it for your web editing. Visit these links below to download, Firefox and Measureit.

When putting images on your site, you will want to measure how big they need to be.
