Block Tag Inside Url_for() In Jinja2
I'm using Jinja2 to render my frontend (and python is on the backend). Each page will have a different image on its top, like this: ![](static/img/pic1.</div>

<div class="answer-desc"><p>What you need is a <strong>macro</strong> to define a kind of function in your template. See this topic in
<a rel="nofollow noreferrer noopener" href="http://jinja.pocoo.org/docs/dev/templates/">http://jinja.pocoo.org/docs/dev/templates/</a></p>
<pre><code id="code_0" class="hljs language-csharp">{% <span class="hljs-function">macro <span class="hljs-title">header_img</span>(<span class="hljs-params">name</span>) -%}
<img src</span>=<span class="hljs-string">"{{ url_for()
>
{%- endmacro %}
>
{%- endmacro %}
You can put this macro in an util template and import it in each page.
Use the syntax:
<header>{{ header_img("your_image.jpg") }}</header>
