Links in Frames work (almost) like Hyperlinks in "single frame" Browser Windows!
EXCEPT...
The Links appear to control other Frames within the same Browser Window. In the previous page example..., the link in the Left Frame controlled the Image in the Right Frame.
Look at this Netscape (Upgrade) Page..., The Frames are top and bottom, rather than left and right!.
(This is an example of Frames..., it isn't necessary to actually Register Navigator... just see how the Frames operate).
