The main differences between panoramax and mapillary are : * Mapillary belongs to Facebook, and Facebook “is” the “owner” of your pictures and could suddenly decide to stop giving free access to Mapillary * Panoramax is open and free (like in free software) and decentralised. Any organisation is welcome to build a repository, shared with all other instances.

Hello, you should rather try to upload to https://panoramax.openstreetmap.fr/ You will get the background map.

The IGN instance is more for France ;-)
