Large image in event detail

Whatever I do, I lkeep seeing the thumbnail image in event detail view
How can i set it to display a full width image?

Ok I finally found the general image size configurations for events, but I'd like the image to be responsive, and fit the full with of the containre box

If I set image width to 100% it goes outside the box and fits the full page

same happens in events list, column view with image thumbnails

Hello

If you want to show large image on event details page, please go to Events Booking -> Configuration, set Display Event Large Image config option set to Yes, then check to see it it works as expected?
