Ah, I see.
I have an older 17" MacBook Pro with a 1920x1200 screen.
On my system the measured display size of the image on the Keyboard Maestro forum is approximately 662x1187 pixels. (Measured with a screen ruler app.)
So Peter must have change the default height of the “cooked” image. It is much larger than what is showing here on the meta forum.
Unpleasantly large — thus my attempt to manually resize it. Take a look.
Are you saying this is the reason the “cooked” image isn’t resized by changing the size in the markdown?
