To add a new 360° photo(s), drag & drop the file(s) onto the map. An import panel will open, where you can name the added 360° photo(s). Click on the image to preview how the 360° photo will look like. When ready, press Upload.
Currently there is no support for 360° photo without Longitude and Latitude coordinates OR without compass heading data (PoseHeadingDegree). Make sure your camera has support for these.
To enter the 360° photo, select the 360° photo and either click on the image or click Open 360° photo. You can then exit the 360° photo from the top right panel upon clicking Back To Map.
To navigate to another 360° photo, click on the markers around the 360° photo or the markers on the mini map (bottom-left) to move to another 360° photo.
