Filesystem Blop or Base64

I have read a lot of this 3 ways to send image across the server, but i still don't get what is the best fit to my project.

Basicly im buildling a native app that has the main goal to shoot some fotos, this fotos should be stored in a database, and retrived in a thing like a feed (something like facebook does with news).

I searched a lot and didn't get any info about the choose on mobile apps, because i know that for example using Base64 will give me performance problems (because i count to have thousands of images in the datbaase), and in a mobile app that is a heavy problem.

But what about the other 2 approaches? i am will use Android app as the client, and postgreSQL as datbase, nodeJS will work on the server.

I ask this because i am really worried about the performance on my android aplication.

Thanks!
