Unfortunately no, I found never a solution for this...
My programming skills are way to limited. To me, it looks like a bug in airport-datas-API. It worked a long time and without doing anything on VRS, it stopped working. So Id say VRS is not the source of the problem. The people on airport-data must have changed something.
I dont know if we can change the picture-provider? I think there is an option to enable this feature in general, but no option to select another provider. I assume airport-data is hard-coded in VRS.
Unless airport-data reverts their API-change or VRS gets updated to use another provider (or let us choose antoher one), I see no way to get the pictures back. But as told above, Im not a programmer. Maybe a simple fix could be implemented, but thats beyond the scope of my knowledge.
