Is there something about the project you’d like to show the world? A photograph of an OSM activity perhaps, or some interesting mapping? Maybe there’s an alternative rendering of our data you’d like to show off, or an application that uses our database in an interesting way.
We show an image a week on our wiki’s front page with the story behind it. You can suggest your favourite picture at Featured image proposals. If people come up with interesting ideas they’ll be shown off to the world.
You can also add a description for each featured image in your language. You can follow the editing links beneath this week’s picture on the wiki’s front page and community blogs or you can use the “Add a description in your language” link in the archive of feature images.
