Here are some basic instructions on how to take screenshots for use on the ITS website.
Guidelines
Use red boxes or red circles to indicate what the user needs to click.
Use a line or box the same color as the background (usually white) to block out sensitive information.
Make sure images and other visual elements are downloaded and fully displayed.
You are welcome to use whatever software you like to take screenshots, but whatever you produce for the ITS website must meet these guidelines.
See below for an example and some methods that are quick and easy to use.
