Discord now allows setting custom images as big and small images by setting a URL instead of the name of the art asset.
This feature is not (at the time of opening the issue) documented on Discord's documentation page. There is a service that is using already this successfully PreMiD with websites as YouTube, YouTube Music and Netflix see Tweet.
This would require uploading the image to a server, as it has to be reachable over http (and probably https). And then setting the URL of the uploaded image as the bigImage.
