Patty,

It sounds like you are using Pub 2003, and by default, right click is
disabled. However, the images are downloaded to your computer by the
browser, and could be copied from the internet temp files. Alternatively,
since you are probably using a fairly low quality image in your website
anyway, perhaps you could upload a higher quality image, and then provide a
link to that image for those who might want to download and print the image.
