When you edit a map in the Openstreetmap website (the "id" editor) you can see each data point by expanding the Map Data menu (line and polygon icon, just below the Background Setting icon), expanding the Photo Overlays section and checking the various Mapillary features. You can both view the images themselves (and filter for 360 or regular pictures), and also look at the traffic sign and map features (manholes, benches, poles, shop signs, etc..) that Mapillary has automatically detected.
