Setting my <img> source to a file path outside of flask static folder

问题

I need to display some images and these image filepaths are outside of flask's static folder stored on on network folders.

<img src="{{ filepath }}"> # /some/external/network/folder/img.jpg

However this is not working and I get a broken image icon, however I can paste the image path into my browser and confirm its accessible. I need this application to be able to accept image sources from anywhere, so I can't update my static folder to the network folder. I also can't load the images to the server because there would be about 20,000+ photos.

Is there a way to get this to work?
