Not Work??

[bcz3]

I just tested it and doesn't work

[X7md]

Sorry, but I do not maintain this lib for a long time...

I suggest you to combine those libraries to do the same functionality:

• rehype-rewrite

 {
          rewrite: (node, index, parent) => {
            if(node.tagName == "img") {
              parent.children = [...parent.children, {
                type: 'element',
                tagName: "figcaption",
                // Optional
                properties: {
                  class: "text-xs"
                },
                children: [
                  {
                    type: "element",
                    tagName: "small",
                    children: [
                      {type: 'text', value: node.properties.alt}
                    ]
                  }
                ]
              }]
            }
          }
        }

• rehype-wrap-all

{
    selector: 'img',
    wrapper: 'figure data-img .text-center'
}

• remark-unwrap-images (optional)
