That's actually because of this quiz that we started to investigate on the French section, this morning, at around 9 am UTC+1 (if the timing can help the moderation).
It's happening for me too, probably because the source website links are broken (don't know if that's the right way to say it but hopefully you get the idea).
For the example that was my quiz they were all imported from my device, so whatever the issue is it seems to be with the site itself, not some external site.
This happened to my quiz too! I sourced my images through Wikimedia and imported them through the photos app so I don’t know what’s wrong. I unfortunately just spotlighted the quiz too.
