Html-jquery How does PHP implement the function of Markdown picture display in SF?

I have a feature like this, when the user uploads the image file, it will be changed to the markdown format address, similar to

![](http://xxx.xxx.com/1.jpg)

I think this way of showing is too bloated and not very good-looking, but also exposes some unattractive directories

I found SF is similar to

![]![图片描述][1]  [1]: /img/bVuIwN

I don't like it so much, but it's a great feature.
The effect I want most is

![](10021555355)// 括号内一串特定的字符

Then I manipulate the DOM through Jquey? Or the other way to achieve this on the right to see the effect of the picture. How do you think it's done?

The directory string should be encrypted, submitted to the background and then decrypted to get the picture path back to the front
