【Help!!!】Base64 pictures cannot be rendered

[Xxianglei]

I use version 0.12.6. centos 7
The base64 image under the IMG tag cannot be rendered. I tried to modify the CSS style of the image, such as width and height, but the rendered image is still a white box

Thanks for the help. I really need it

image:base64、jepg

I found a workaround

<img class="shot" id="screenshot"  alt="" src=""/>

.shot{
    background-size: cover;
    margin:auto;
    width:1000px;
    height:600px;
    opacity:1.0;
}

But opacity doesn't seem to work

Who can help me with this problem
