Add the attribute spinner to true for set the loading spinner instead an empty image.
The attribute size is the size of your spinner_container (by default is set to 100 or your default value configuration).
The attribute wsize is the width size of your spinner_container
The attribute hsize is the height size of your spinner_container
The attribute fadein will display your image with fadeIn animation to your opacity value (20fps)
Values can be set to pixels, percentages, and viewports.
The spinner will be half the size of your container.
Your spinner will be display as :
<div class="spinner_container">
<div class="spinner"></div>

The module detect the DOM inserted images and updated images, and actualise spinners while loading.
