[GeoNode-users] Base layer is not visible on thumbnail of the uploaded content

[Naresh N]

Dear Jonathan,

Thanks a lot for detailed explanation.

It may be good , this kind of functionality  may be implemented in newer
version of GeoNode, since with out base layer the thumbnail does not
looking good, user has to manually set

When we delete the layer/map the corresponding thumbnail is not deleting
from the server. How to delete thumbnails in case of deletion of layers/maps

Thanks&Regards,
Naresh
