Why does wordpress generate more thumbnails than the 3 standard sizes?
If I upload an image in WordPress, it usually generates more images sizes than what I have indicated in my settings -> media (small 150, medium 300, large 1024).
For example, if I upload a 4K image, it generates up to 7 more copies + the original (150, 300, 768, 1024, 1536, 20148, scaled, original).
I’m using a child theme based on Underscores, but it seems that no file functions tell WordPress to generate the other copies.
Where do they come from?
