How to store images correctly in redis?

There are a few ways to store images in Redis, depending on the size and complexity of the images:

1. Store image data as a string: If the image is small and can be stored as a binary string, you can store it directly in a Redis string data type. You can use the SET command to set the image data as the value of a key.
2. Store image metadata in a hash: If the image has metadata associated with it, such as file name, size, or format, you can store this information in a Redis hash data type. You can set the hash field as the key and the metadata as the value.
3. Store image data in a Redis list: If you have multiple images that need to be stored together, you can store them in a Redis list data type. You can use the LPUSH command to push new images onto the list.
4. Store image data in a Redis set: If you need to store unique images and perform set operations on them, you can store them in a Redis set data type. You can use the SADD command to add new images to the set.
5. Use Redis modules: If you need more advanced image processing capabilities, you can use Redis modules such as RedisGears or RedisAI to store and process images in Redis.

Before storing images in Redis, make sure to consider the size and complexity of the images, as well as the performance and scalability requirements of your application. Additionally, you may want to compress or encode images before storing them in Redis to optimize storage space and improve retrieval speed.
