Replace the jpgwith the type of image, and [your byte array]with your byte array. You need to convert it to base64if it isn't already.
将 替换jpg为图像类型，并 [your byte array]替换为您的byte array. base64如果还没有，您需要将其转换为。
<img id="profileImage" src="data:image/jpg;base64, [your byte array]">

In my case the base64 byte array had to be chunked, in the way:
在我的情况下，base64 字节数组必须分块，方式如下：
<img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEASABIAAD/4QCARXhpZgAATU0AKgAAAAgABAEaAAUAAAABAAAAPgEbAAUA
AAABAAAARgEoAAMAAAABAAIAAIdpAAQAAAABAAAATgAAAAAAAABIAAAAAQAAAEgAAAABAAOQAAAH
...
To make this solution works.
