Integration module lazyloader

When we used the module lazyloader, the render image style the altera:
<img typeof="foaf:Image" data-src="/sites/default/files/styles/xxx.png?itok=A-8nau7I" src="/profiles/...../image_placeholder.gif" width="120" height="120" alt="" /><noscript><img typeof="foaf:Image" src="/sites/default/files/styles/bxxx.png?itok=A-8nau7I" width="120" height="120" alt="" /></noscript>

Show insert two the label img, the module view data source insert the image twice output json. With this patch could user the module lazyloader and view datasource.
