Quite easy actually—I go to Wikimedia Commons and find these flags, then I add these images by entering their URLs in the Picture Quiz format.
Sometimes I removed words on the flags that gave away the name of the territory, then uploaded them to Wikimedia Commons so I can use them on this quiz, but seeing the low average score I think it would have been better to just leave the flags in their original form.
