Does just what I need

Thanks! this plugin was just what was needed to supplement the various page headers used throughout my site.

One note, if you’re doing a conditional you can check if an image was uploaded for the current category using this:

if (function_exists('z_taxonomy_image_url') && z_taxonomy_image_url()) {
     echo '<img src="' . z_taxonomy_image_url(NULL, 'page-header') . '" />';
}
