FullCalendar - Images as events

Looking to use Full Calendar and to include images as events and draggable. In short, would love to see how this example https://fullcalendar.io/js/fullcalendar-3.0.1/demos/external-dragging.html would work with small thumbnails instead of the text "My Event 1, My Event 2" etc. And have that image show up on the calendar.

Thanks in advance.

You can add any image url to your eventObject by adding the attribute "imageurl" inside of the events definition (if you just want the image, don't specify a title):

events: [
    {
        title  : 'event',
        start  : '2016-10-12',
        end  : '2016-10-14',
        imageurl:'img/edit.png', //you can pass the image url with a variable if you wish different images for each event 
        .
        .
        .
    }

After that, you add the following code in the eventRender, which will add the image icon to the event (16 width and height is a good size for a thumbnail):

eventRender: function(event, eventElement) {
    if (event.imageurl) {
        eventElement.find("div.fc-content").prepend("<img src='" + event.imageurl +"' width='16' height='16'>");
    }
},
