Improve Radio Broadcaster#798

It would be nice to have choice to display or not the cover of current artiste - title, with the choice of an API that you set up with a community database image we can complet from our dashbord, or that we could put an html code to display the cover of a widget from our radio managers and the most well-known suppliers. Or a url of a fixed image, example https://livemusicradio.fr/lmrcover.php (this page when it is called every x seconds displays the image of the title currently being broadcast on the radio server).
