Sorry I didn't catch that one the first time, but the path should be ${path}/static/images/contributor-survey-banner.png.
The ${path} variable will then be substituted to the correct base path depending on the target environment (which is / in production).

The class img-fluid is also not defined anywhere.

That's super weird... that is not a file that was edited or relevant to this PR and wasn't touched by git. I'm not sure how to explain what's in that commit there. However in the actual files changed, I added ${path}. I'm not sure about the img-fluid thing, that's a normal bootstrap class that is in version 4.

This website still use bootstrap 3.0.3 ... :/

I don't see any irrelevant files in this PR, so I guess it's only the commit message that got messed up somehow, nothing to worry about.

I guess it needs some styling to replace the missing img-fluid class.

Hey @lilyx, do you need any help going further on this PR?
I can merge it and try to figure out the missing css styling on the banner if you want me to.

Closing as not needed anymore
