Sending images as bot responses

I would like to know how to enable bot to send images alongside text information that contains long paragraphs. I tried using dispatcher.utter_custom_message but it doesn’t seem to work well. Can someone explain how to output text and image together?

thanks for your post! can you please be more precise about what “doesn’t seem to work well”? Which messaging channel are you connecting to? (e.g. slack, facebook messenger…)

I am using the slack interface. And I have solved my problem. Apparently slack auto-downloads images after passing the image link as a response therefore automatically displaying the image as response message. Thanks for the reply though!
