For example, imagine a wine company. The user asks what is the best wine of 2020, and the bot answers about an especific wine and the image of the bottle. How can I do that? Is it possible if the image is in the KB? Any workarounds?

Hi ! If you store your products in a table , with an image and a description for exemple, you can set this table as a database and perform a search on it, or / and use the “find records” card based on the user input

I need to store the url of the image?

Yes you can add a field img_url for example
