You may want to change out more than one frame someday with one link.
1. Make a frameset
2. from your link type in the code:
<a href="javascript:location='links.html';
parent.topright.location='logo1.html';
parent.bottomright.location='content1.html'">
click here to change</a>
explained:
"javascript:location='links.html'; <!--this will
reload the page that the link comes from. If you want the same page in there,
just link to it-->
parent.topright.location='logo1.html'; <!--this
is going to replace the frame named "topright" with a new page-->
parent.bottomright.location='content1.html'"<!--this
is going to replace the frame named "bottomright" with a new page-->
