Not being one to sit around waiting I did a bit of digging to try get this going.
I found this:
1) Under header.php, if you find “div id=header”, you can edit what links it has in place.
2) To get the map to play nice, the map id needs removing and the name needs simplifying. I went with “map” (only one we’ll be running).
So, where initially we had this (followed by the front page identification tags):
$header_img = '<img src="' . $header_img . '" alt="' . $alt . '" width="' . HEADER_IMAGE_WIDTH . '" height="' . HEADER_IMAGE_HEIGHT . '" class="header-img" />';
We now have this:
$header_img = '<img src="' . $header_img . '" alt="' . $alt . '" width="' . HEADER_IMAGE_WIDTH . '" height="' . HEADER_IMAGE_HEIGHT . '" class="header-img" usemap="#Map"/>';
And below the header img section (after closing that php area), I’ve added this:
<map name="Map"><area shape="rect" alt="TEXT 1" title="TITLE 1" coords="0,0,1018,132" href="URL 1" target="" /><area shape="rect" alt="TEXT 2" title="TITLE 2" coords="1,134,1019,185" href="URL 2" target="" /></map>
So what we’ve achieved is an image as the header with a map overlaid on the image. The map then contains fields allowing multiple links overlaid on the header image.
Problem solved.
