I also just started having this specific problem today. Yesterday, everything was fine.
I can see images of games including thumbnails and the images it flips through until I actually go to the game's page. Once I go the the game's direct page, none of the images load. After a few moments, the images error out and leave the placeholder icon for the main image and the example images underneath the download links. This is the case with both my PC and my phone.
I assume it's just a website issue and plan to wait it out. I'm in the Midwest United States and have the issue with both with/without a VPN.
