Where you store them is up to you. send_file should work with any path that the server has access to. Maybe “/uploads” under your project folder? You would create a route to a controller where the parameter allows you to find the file. That route, with appropriate parameters to find the image f…

Wow. It is so simple. Thank you very much. I appreciate your time and effort. I would love to see the code snippets as well.

I went digging and remembered that I actually used a very good online tutorial to learn most of the tricks I needed to get this work. Here it is: Step-by-Step Tutorial to Build a Phoenix App that Supports User Upload I didn’t do a lot of what was here (e.g. I didn’t want the ImageMagick dependency)…

Ah thank you. I have stumbled upon that tutorial as well. I will experiment a bit. I think I should look for production elixir apps and study them.

Note that if you will ever run on more than one server, this technique is not sustainable as you will get irregular 404s based on which backend node you connect to on any given file request. This is why the S3 approach and similar techniques are so desirable, and as a bonus they help pave the way fo…
