Ostrio:files server side image upload


hi guys i am using ostrio:files package, i want to upload an image on the server side and get the image ID to input for my other data. But i couldn’t find any documentation on upload on server side


seems to get stored in /var/lib/docker/overlay2/[some id]/merged/built_app/programs/server/images
But somehow I don’t have permission to go there since ‘sudo cd’ is not a thing. Maybe upload to server and then ‘sudo mv’ them to this location?
