Answer 1

You can store images anywhere you want depending on its security concern. If those images can be publicly accessible you can send its url/path in response which can be set as src by angular js app. But if its a security concerned and it will be according to role rights implementation then you should return as multipart/form-data (base64) in response. Later on this will be set as src="data:image/png;base64,<YOUR_RESPONSE_DATA>
