Change or refresh folder background via script or cli?

Hello, I would like to change my folder backgrounds every couple of minutes like a slideshow. is it possible to set a new background image via script/command line or tell dopus to reload the current image from disk? The only way i found is closing dopus completely and then replacing the current image on disk with a new one and then start up dopus again but that is not very practical, i need to tell dopus to reload the current background from disk or set a new one while it is running.

There isn't a way to do that, at least at the moment. The way background images currently work, they'd all need to be defined in advance. (Something we're thinking about changing, but not sure if/when or exactly how yet.)

Any update on this?

No. it's not something that will change in the near future.
