Nimble Post Grid not working since Update

Hi, I permanetley have to roll back the plug-in to Version 1.10.12, because ever since then the Post Grid Module wan’t show the images. The problem is mostly with firefox, but also in the mobile version, the images are loading too slow or not at all. The perfomance of my page is not good at all with the new updates.

I don’t know what to do about it, I disabled other plug-in’s to find out wether it there is problem or not. But it is not the other plug-ins, it is the UpDate. Because the old version is working fine.

Thank you.
