I noticed while creating webinar preview cards for a series I was creating that the recommended size (300x200) results in the left and right edges of the image to become cropped on the listings on the series page (which is a problem when using logos or other images that need to displayed in full). I got around this by creating more margins on the images, but it would be great to prevent this from happening, either by changing the recommend size or by preventing any crop in the first place.
