problems with the images on the home page

Hi there,
I can see two posts (displayed in a grid) on your home page and they both display a thumbnail:
wp-content/uploads/Hermann-Rorschach-en-1910-1-570×350.jpg
wp-content/uploads/Sigmund-Freud-en-1926-1-570×350.jpg

Have you already fixed the issue?

no, the problem is that the images are not scaled, they are shown as their original weight.

Sorry cannot see it.
e.g., the first post:
this is the original image: https://psicologiafacil.com/wp-content/uploads/Hermann-Rorschach-en-1910-1.jpg
this is the shown thumbnail (scaled version): https://psicologiafacil.com/wp-content/uploads/Hermann-Rorschach-en-1910-1-570×350.jpg

the problem is that when doing a speed test it appears to me that the images should be reduced or servings scaled to improve the site
