Thanks for the information. It definitely sounds like your connection is blocking out images. All images on itch.io are served through the same server though, so I would think that either all would be blocked, or none. Other images on the site load fine?

I'm somewhere else atm so I'm not 100% sure, but I think the logo in the top left loads fine but definitely no avatars, game preview thumbnail images, game page banners, screenshots or backgrounds. I think when looking through forums a few images people posted weren't loading either but then others would, so might be that the ones which would load were hosted on another site by the poster (it was a devlog which I remember loading, I think it was just a bug submission or something which wouldn't load).
