After looking at the generatepress code, I noticed crop would be turned off if I didn’t set both a width and height value. So I only set the width hoping that would keep the image optimizer from running. This is enough for the Jetpack CDN to resize.
Not sure if it’s working, but so far my wp-options table is not filling up with image processing entries even though I do NOT have this set: define( ‘GP_IMAGE_RESIZER’, false );
If the db remains clean for another day or so, we can mark this issue as resolved.
Thanks.
