I am developing a chatbot using NodeJS and BotBuilder. I have the file chatbot.jpg stored in a folder named image. This sits just beneath the root directory. I am able to display the image (using Kudu to find the URL) in a web browser as follows:

<https://mysite.scm.azurewebsites.net/api/vfs/site/wwwroot/images/chatbot.jpg>

If I remove the .scm element within the URL, I can no longer display the image. 

Even more curiously, if I use the above URL in my bot code, the image doesn't display.

```
var welcomeCard = new builder.HeroCard(session)
.title("This is the new")
.subtitle('Virtual Assistant')
.images([
new builder.CardImage(session)
.url("http://mysite.scm.azurewebsites.net/api/vfs/site/wwwroot/images/chatbot.jpg")
alt("Virtual Assistant")
]);
session.send(new builder.Message(session)
.addAttachment(welcomeCard));

```

My question is, how do I find out the regular URL of the image stored in the Azure App Service, so that I can use it in my code?
