Import layer with attached pictures or drawing

[SygPi]

I'm trying to import a Geojson file with attached pictures. I tried to make the same structure as when I add a picture to a point but without success. Anybody can help me?

This is not possible.
Current version (2.x) has no such functionality. In coming NextGIS Mobile version 3 panned the functionality to download attached images from NextGIS Web (cloud nextgis.com).
