Other than the mouseover effects that are most used for highlighting
buttons instead of popping up images, here, this page shows how one can
nest TABLEs inside each other to control the layout of a web page.
Replace the BORDER=0 with BORDER=0 attributes
inside each of the four TABLEs to see the complexity of the layout
required for this page. In order to appreciate that complexity,
remove all the TABLEs and try to make the page work without having it
constantly resizing itself. (Note also that this is a case
where the percentage (%) method of specifying each TABLE's WIDTH is
preferred in order to preclude sums greater than 100%.)
