Getting & Using Images
and uses of images:
Taking photos with a digital camera is easy, and the images can be added to web pages. Here is a picture of me in the Northwest Campus Library at El Paso Community College, where I teach. Photos can be easily modified and placed where you need them. Here, to the right, is the same photo cropped.
|You can also easily make charts and tables to illustrate points. Below are two graphics I made with a simple program that comes installed on most new computers. Both are for a course I teach in World History. The first is to illustrate the various forces that an emperor in China might have to deal with. The second is intended to illustrate one of Plato's concepts of government.|
|Such graphics can be made in just a few minutes in Paint, one of the simplest programs to use -- and one of the most powerful. Almost all of the images in this module were made originally in Paint. Below is the graphic to illustrate Plato's concept of government.|

The handout was originally made in Word and converted to a web page in Word.
|I made the image to the left to add to a handout after seeing something like it in Bertrand Russell's book, Wisdom of the West. The graphic was put into a web page that is suitable for uploading. Students can either view it online or print it out should they want a hard copy of it.|
images by making them:
If a digital camera does not allow you to save images in these formats, simply open them in Paint and convert them to the JPEG or GIF formats. They are then ready to use. JPEG and GIF are formats for storing images. The JPEG format provides a sharper image, but GIF images are smaller. Neither takes up much room, which is a big consideration when having to transport images or store them on the web. To illustrate the difference, here is the file size of the "Forces in Politics" graphic above. I created it in the default format (called "bitmap") of the Paint program. It's wonderfully sharp, but the files are enormous. See for yourself:
In the bitmap format, you could store only one of these images on a 3.5-inch diskette (which holds about 1.5 million bytes, which is to say 1.5 megabytes). In the other formats, you can store many more images. And because they are smaller files, they open faster on your web pages.
You can also use Paint to make images. The program is usually installed under "Accessories" on the "All Programs" list accessed with the Windows "Start" button. The various tools for creating images are icons for drawing lines, making squares, circles, and irregular shapes, for adding color, and for manipulating the image. It's a very easy program to become familiar with, and you can learn it by opening it and just beginning to "tinker." The exercise associated with this chapter will help make you familiar with it.
I have created two sets of graphic images as examples. One is on the page titled "Image Table," which is mostly pictorial images. Some, as you can see are more successful than others. All were done with the Paint program and drawing with the mouse. On the "Instructional Graphics" page, I have placed some graphics I designed with the same program to convey conceptual material.
The directions in the exercise will walk you through how to make such images.
New scanners are so simple that almost anyone can quickly create images that can adorn web pages or PowerPoint productions. Many computer labs have scanners for use by clients. If you don't know how to scan images now, ask someone to show you how. It's easy. Just remember to save them in the .JPEG or .GIF format.
graphics from the web for use in classes:
The nice thing about the web is that such materials are easy to access. I sometimes build web pages that I store on my desktop and use only in the classroom (with a LCD projector or monitor large enough for the class to see. When I harvest such materials off the web, I always create a "Source" link right next to the image. If I have Internet access when I display the page, I can go to the original site. It also has the added benefit of giving credit to those who created the site.
Such images are easily harvested from the web. All you have to do is put the cursor on the image, right click on the mouse, and follow the directions for saving the item in an appropriate folder. You will get practice in doing this in the exercise for this chapter.
Because of recent concern over intellectual property restrictions, especially the "Digital Millennium Copyright Act," it's a good idea to become familiar with the restrictions. Stanford University has a superb discussion of current US law with respect to these matters on its web site called "Copyright and Fair Use." Of interest in this short course is the section titled "Proposed Educational Guidelines for Fair Use." Section 2 is particularly relevant, as it deals with "Proposed Guidelines for Using Digitized Images in Lectures, Scholarly Presentations, or Publications."
(If you can get permission from those who created it, that's even better. Often a web page has a source to contact about the page. I would start there in my quest for permission. You can avoid all that hassle by creating your own images. As for the images in this module, you may use any of them that you think might be helpful. I will tell you from personal experience, however, that it's a lot more fun to create your own.)
