interesting concept, embedding the clickable area in the TIFF needs 
5 (private) tags per area: {x, y, width, height, URL} or at 
least 3 { x, y, URL} using a closest point algorithm. 

Drawback: manipulating the image could corrupt the integrity and 
validity of the area params if they are preserved at all. 
(integrity tag needed)

Still it offers interesting possibilities ...

rob
