Problem with viewing Wikipedia images - resolved by turning off Anti-Track

I suspect this may be a recent change to Anti-Track, but starting a couple of weeks ago I suddenly could not see most images on Wikipedia in any browser on my laptop. I raised this issue on Wikipedia’s “Village Pump” area, and someone advised to check my security software for ad-blockers and so on that might be blocking Wikipedia’s content servers, especially domains “commons.wikimedia.org and upload.wikimedia.org”.

Not knowing what else to do with Avast in this regard, as an experiment I turned off Avast Anti-Track. And immediately I was able to see Wikipedia images.

I’d submit this as a “bug” if I knew how to.
