Remon, hi again! so I set transparent thumbnail, created mu-plugin and paste your code, not sure how it suppose to work, sorry, I’m a frontender…
Let me explain my case specifically — it’s woocommerce store, almost all images square 400×400 with white background.
So I wonder if I can place that 400×400 image as it is on the right side of 1200×630 og image with text.
If you please be kind to explain me more detailed where should I place your code I’d be greatfull.
