When you are asking the user for their files/images, you may want to use a special input type called file/image input type, which you can select from the Input type Drop Down menu.

Once the user responds on it you have the collected the files/images which the user has uploaded.

In the data section/Email notification this data or image or file gets transformed to a unique link. But some people might want to use this unique link directly in the chatbot

So referencing is used in this case.

If you are collecting the image on a gambit named "file_upload" then user can type a code to access the unique link which is {{uval.filename[0].file_url}} or in the above case the code would be {{uval.file_upload[0].file_url}}.

For reference look at below picture

And this is how you get the unique link to the images/files.
