    This was EXTREMELY helpful. Thank you so much! It would be great if JetPack would create thumbnails proportionately to the image they are grabbing rather than random cropping.

    This is great. But I am a little unclear where I should add this coding?

    Trying to change the thumbnail size and used the code above in my child theme’s functions.php.
    Doesn’t work for me, unfortunately. Any ideas? Does it take a while for Photon to display the new size?
