I get what you mean but that is not possible due to a Kodi limitation.
What I can do however, is that you can store image 0.png in your custom folder that will be used as fallback..

Should this work already with "0.png"?
It was "default.png" in the past, right?

I'm not sure how it worked before. I just made a change to the code to have 0.png as fallback image. Will upload new beta tonight, currently enjoying the weather at the pool ?

Have fun!!!
