The "../images" means that it is at the address:
"http://cs.wpi.edu/~kal/public_html/images/blueball.gif" (You can piece that together by looking at the URL at the top of your view).
You can use this URL in any of your pages to show a blue ball.
Help yourself to (download) a picture: Move your mouse to the blue ball , and click the right mouse button. If a menu appears, you can save this. To move it to the same account as your html documents (or better: make a subdirectory under public_html called "images" and FTP it there. (Don't forget chmod on both the directory and the file).
Scan pictures in (if you have a scanner)
