Add information (name, source, copyright) to an image -- using Netscape
Composer
In your html page, click on Insert Image (browse and select the image
file),
then add the information to Alt/text and tool tip text.
This may not work in Blackboard but it will show up on a regular web
page when your mouse points to the image.

You can copyright an image but you need not worry about that in web
resolution (72-96 dpi) which is not good enough
for
print.
