Hi, I created a small plugin:

```auto
module Jekyll
    class RenderImgTag < Liquid::Tag
      def initialize(tag_name, variables, tokens)
        super
        @variables = variables.split(" ", 2)
        @url = @variables[0]
        @alt = @variables[1]
      end
      def render(context)
        "<img src='#{@url}' alt='#{@alt}' />"
      end
    end
  end

 
  Liquid::Template.register_tag('render_img', Jekyll::RenderImgTag)

```

Its mission:

`{% render_img https://exampleimageurl.com "my alt text" %}`

Its working great, but I need to include liquid variable. Like this:

`{% render_img {{post.image.src}} "my alt text" %}`

But its not working. How can I do that?

Possibly you don’t need to quote the variable reference with `{{ }}`? I.e.:

```auto
{% render_img post.image.src "my alt text" %}

```
