Hi Andy,
I added the code to my css file and it looks like it is working. I did noticed however that the imagesLoaded script is fired. I saw this line in my html output:
<script type="text/javascript" src="http://stockphotosite.dev/wp-includes/js/imagesloaded.min.js?ver=3.2.0"></script>
I don’t know if it is called but still…. I thought to let you know.
I suggest to keep the thread open for a while. I will test it further and let you know.
Best Regards,
Adri
