Image in banner topic

[helperhaps]

My Discourse version is v1.6 stable

In my local discourse, it is not install under docker. I run it with rails s. I uploaded a random image. And changed its width from 690 to 100% to make it look more better as a banner.

Then make it banner. It works just well.

BUT when i do the same thing in docker env, It changed

I have no idea what to do with it, but who can tell me what happened and what to do with it

On your local dev are you running sidekiq? Because this looks like the image processing is kicking in and adding the lightbox to the image.

My bad.

But it could’t be that. How to make the image in the banner ? It looks not so good when the image like this.

The right side of the banner is blank.
