Before you think of taking the images or text on this

A user copying text or pictures from this web site and then
posting the material among the user's own web pages is infringing our

Internet to have the freshest information is to have only the author post

Copying illustrations or diagrams or photographs (e.g.,
scanning a printed image or copying a GIF or JPEG file) always requires

ask permission of the copyright owner before displaying any copyrighted
