Comment (by joyously):

 > I'd like to suggest the Settings > Media page display the current
 $content_width, as well as explain a bit, as well as link to a deeper
 explanation. As it is, a user can select a theme, blindly set the image
 sizes (not realizing who they actually map to the theme), and then be hit
 with the experience (?) described above, AND have no idea why.

 The problem with this is the sizes on Settings > Media page applies only
 to images uploaded ''after'' you change the sizes. And the content width
 is different for every theme, which can be switched at any time, including
 programmatically for each page (like a Theme Switcher plugin). And the
 actual width is different for every visitor's device window.

 This is why there is another ticket to remove the image size options,
 since the sizes computed for the browser to choose from are based on the
 largest uploaded.

 I don't think adding explanation here will be helpful when the thing being
 explained is a moving target.
