The path to your image is pointing to your own system. You need to change it so that it points to the location of the images in your web space.
For example, if your document is in your root directory and your images are in an images folder in the root directory, you would use this:
<img src="/images/onebyone.gif" height="n" width="n" alt="alternative text> (n= the actual height and width of your image).
