Currently in the flow any file (image/ documents) need to be downloaded in to the device before we can view them. Flow does enable displaying images in the user step, but they need to be be deployed into ftp or other hosting location.

We commonly gets asked from the customers for the possibility of preview/view this documents within the app without needing to downloading to the device.

Downloading the files to devices will cause files been left in download folders reducing the disc space as well as making too many copies of the sensitive information.

Some customers has gone to the extent of connecting addon features to perform this functionality on their own services outside flow.
