The discussion revolves around an issue with displaying an image in a banner on a Discourse forum. helperhaps is experiencing a discrepancy between their local development environment and a Docker environment. In the local environment, the image is displayed correctly as a banner, but in the Docker environment, the image is altered, with a lightbox effect and a blank space on the right side. Falco suggests that image processing might be the cause, but helperhaps is unsure and seeks help on how to properly display the image in the banner.
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.
