This is a great way to quickly locate web pages about a particular subject. If you find an interesting site that you may wish to return to, select the Bookmarks dropdown menu at the top of the screen, then click on Add Bookmark to save the URL of the page you are currently viewing. You can then easily access this page later from a list under that same dropdown menu. A menu will pop up allowing you to save the image. Be careful, as you don't want to go over your disk quota.
Images come in many formats, the most common being gif and jpg .
One format can be converted into another with a variety of tools. Look at our Software at Math Department section to find out about these tools. In general, jpg files are smaller, and therefore prefered.
