media – Automatically Insert alt attribute above image has h2


When inserting an image in a WordPress post, I would like that it automatically add the alt text of the image above the image as h2.

Example, when inserting an image, WordPress ads this into the post:

<img src="" alt="Hello" />

What I would like is inserting:

<h2>Hello</h2>
<img src="" alt="Hello" />

Thank you for your help!

Best regards
