How do I store images correctly in Redis or Valkey?

Decided to store images in Redis, how to do it correctly? Now I do this:

$redis->set('image_path', 'here is the base64 image code');

I'm not sure this is normal.

It is perfectly ok to store images in Valkey/Redis. Keys and values are both binary-safe

Strings are binary safe, this means that a string can contain any kind of data, for instance a JPEG image or a serialized Ruby object.

A String value can be at max 512 Megabytes in length.

You can store the image in binary instead of base64 and it will be more efficient:

• In RAM memory usage on your server
• In Network usage
• In compute (CPU) usage assuming you are passing the images in binary to the final client

You can do

$client->set('profile_picture', file_get_contents("profile.png"));
