Resaving PODS helped me too.
When I exclude theme files ZoxPress from Async Java Script and turn off Autooptimize everything works fine. So somewhere there happens problem.
I have hit the completely same problem. After doing bulk compression some of the images just disappeared from the home page (vrmojo.de). They are displayed correctly if I visit website when I am logged in. But when I am not logged in they are just not there.
Everything worked fine until I run bulk compression. It looks to me there can be some kind of problem with plugin.
