I have used and just tested again the
Dynamic Headers plugin. Atahalpa makes this plugin very easy to use. You just install the plugin, replace
%image with
<?php show_media_header(); ?> in ATA>Style & edit
HEADER AREA>Configure
Header Area. Then you go to whatever page you want to change the image for and select the picture as outlined in the directions for this plugin. You can choose to have a default image or not in which case there will be no
header image. I'm thinking I might make this a default plugin for all my installations.
