Why not add the border using CSS?

It’s 1 line of css. Also, we can’t predict how ImageMagick will scale down an image. We can’t ensure that 1 pixel borders are never removed…

Sure, feel free to write a whole plugin to overwrite how Discourse generates thumbnails (instead of 1 line of CSS) just to add borders :wink:
