If you look at any Google local result, the local knowledge panel section, and look at the images section, it will load a blank white section. The images are not loading in the local knowledge panel section for any local knowledge panel - and I've tested a dozen or so.
This is both on desktop and mobile, it simply does not load. I am sure it is a temporary bug but I wanted to let you know that you are not alone, this seems widespread. So don't go ahead and start updating your images, Google will hopefully fix this soon.
Here are screen shots from my knowledge panel:
Forum discussion at Twitter.
Update: This is now fixed as of 10:30am EST.
