Panoramax – Open Street Imagery

Interesting project! Is it an open source alternative to streetview, mapillary or KartaView/OpenStreetCam? I guess an "about" page would be nice to have :) (edit: on panoramax.fr one can read more about it it seems)

And it is stated that it is compatible with ODbl but the wiki here:

https://wiki.openstreetmap.org/wiki/Import/ODbL_Compatibilit...

says it is not. Likely I'm misunderstanding something.
