should be either GIF files or JPG (JPEG) files. Do not try to copy
and paste images into the Web Pages that you create. For a simple website,
you need to save the image files into the same folder as the web pages that
you are creating. If you need an image from the Web, the image can
be saved by right-clicking on the image, then clicking Save Picture As...
(or Save Image As...).
If you use any graphic image that you did not create yourself, be sure to include appropriate attribution for the image in your bibliography.
