Answer 1

Converting binary data into image is not related to ReactJS, If you have the binary data then convert it into image like this:

<img src={`data:image/jpeg;base64,${binary_data}`} />

Answer 2

The given approach is right,

<img src={`data:image/jpeg;base64,${binary_data}`} />

If your image is not rendering, please check your binary string, if the data:image/jpeg;base64 is already there, then please use the {binary_data} directly. Like as

<img src={binary_data} />
