The image preview of my facebook posts from my laravel web application do not work. I have been advised atleast by the facebook debug tool to explicitly specify the og meta tags. This however needs to be defined dynamically and not hardcoded.
When using the local driver, all files that should be publicly accessible should be placed in the storage/app/public directory. Furthermore, you should create a symbolic link at public/storage which points to the storage/app/public directory.
