Images are being automatically cropped

I’m not a graphic designer so my apologies if I don’t use the proper terminology. Some of the images that I’ve uploaded to the media library are being cropped at the top. It only happens with the images that have substantial height. Please give me some guidance on how to correct this problem.

Here’s an example: See the Crain’s image: https://www.xhtmljunkies.net/wordpresstej/wordpress/press/?preview=true&preview_id=20&preview_nonce=eaad25b957

Thanks in advance for your help!
