There is if you're willing to break apart some theme code. You'll need to stitch together a few changes to make this happen.
- Map Generation.
You're going to need some front-end tool to select your geometry and map it to hyperlinks. It sounds like plugin/module you found may do this. Failing that, it's pretty easy to find existing online tools to do this: Example #1, Example #2, Example #3. It should generate some
area elements for you.
- Storing Maps
Here you're going to be altering the form array/submission-handler in theme-settings.php & template.php so you can store the maps for each image. There are few parts of this to change:
_marinelli_banner_form($image_data): This generates the subform that contains all the image form elements. For simplicity, you can add a textfield form element called
image_map that will contain the map/area markup for each image.
marinelli_settings_submit($form, &$form_state): This submission handler will need to be altered so you can store the map/area data. A likely area would be the 1st foreach block where you can take each
image_map and store it into the
This should be it here. The get/set functions
marinelli_set_banners are creating a complex array that gets stored into
theme_marinelli_banner_settings so no additional data structure altercation should be needed. All you need to do is add the image_map element for each stored image.
- Displaying Maps
Here we're looking at logics/banners.inc to alter the rendering. This PHP include contains the banner element markup in the template.php:
marinelli_preprocess_page(&vars) > page.tpl.php:
$banner_image rendering pipeline.
marinelli_banner_markup($banners): Here each
$banner should have an array element
image_map that we defined before. It's using theme_image to generate the image. It should be pretty easy to add the
usemap element, and output the
map/area markup we've stored. There is also some logic for wrapping the image in a link that needs to be scrubbed out.
marinelli_banners_add_js($num_banners): This function adds all the JS sources/settings to fire up the slideshow. It may need to be tweaked to make sure the maps cycle correctly when the changing images.
