Where do I add imagemap in drupal 7
As none of my attempts were working, I tried a completely new approach using views.

I've created a new content type named 'banner'. And in the body field, I've added an html img tag and map tag(for image mapping). Now, I've created a view with format as slideshow and field as content:body. Creating a block for this view and adding it in the advertise region (in marinelli theme) replaces the rotating banner image in Marinelli theme. 

Before adding the view in advertise region, we need to disable the original theme banner. For this, goto admin-&gt;appearence-&gt;settings-&gt;marinelli-&gt;Banner configuration and choose 'Drupal region (advertise) for the question Do you want to use marinelli banners or a classic drupal region?
