When I inserted this image into a test page before writing my post below, Kinja copped the image the way I wanted and it looked like this. But as the post appears on the Observation Deck the image is cropped a little differently.
The ODeck is the only place it's cropped like that. When I go to my public page, it looks the way I wanted. It looks like the aspect ratio of the ODeck image is slightly different from the ratio on the other pages I have checked the post on so I figure that may be the cause of the different cropping.
Is this a major issue? No. I could just crop the image myself to the right size and swap it out. But it's something I have keep in mind ... at least until the next iteration of Kinja anyway.
