Is there some way to substitute the http or streamed image with an image file? I'm trying to figure out how to publish something other than "No device selected" or shutting the software down which results in a 404 page not found error when I want to temporarily disable the live image. There does not seem to be an "offline" function and I understand that the "offline image" feature is not fully functional.

Thanks,
