title: How do I change the background image on an Alexa Show skill card?
body: <p>I'm new to programming Alexa skills, especially with the Echo Show. I am trying to change the background image of the skill card from the default dark grey to something else. I know there has to be a way to do this because when I say, "Alexa, tell me a joke." that skill's background is red. And when I say, "Alexa, tell me about LeBron James." Alexa changes the background to LeBron James and the text auto scrolls. Any help on this would be great.</p>
