I can't find where to add the imagefit code to galleria plugin. I
would really appreciate some help here.
=========== begin imagefit instructions ========
In your JavaScript
Where '#content' is a jQuery selector for the container (or
containers) inside which you want images to resize:
$(function(){
$('#content').imagefit();
});
============ end imagefit instructions =========
============ galleria plugin =================
