Facebook pushed upon its users a number of design changes. A new Timeline, condensed commenting and other things some of which I’m okay with, some are bothersome, others I hate.
One thing I hate is how they recently decided to display a users photos. It doesn’t feel right. See examples below.

This is Facebook's redesigned photo viewer. They added a sidebar on the right for comments and ads. The problem is that horizontal images look like the right side of the photo has been chopped-off by the sidebar, like you're missing something. Bad design as it feels like it's choking the image.
