Image into a post

As I realize, wordpress is inserting <img src> into the post…. which I do not like, and trying to improve it by inserting <figure> tag, with mikrodata, ex:

<figure itemprop="associatedMedia" itemscope itemtype="https://schema.org/ImageObject">
	<img src="small-image.jpg" itemprop="image" alt="Image description" />

	<figcaption itemprop="caption description">
		Long image description

		<span itemprop="copyrightHolder">Photo: AP</span>
	</figcaption>
</figure>

Everything a I found are plugins which “trigger” on “insert to editor”, instead to trigger on shortcode on output, so, I have to “reinsert” all the images.

I can say, this is wrong concept.

Images should be inserted to editor with shortcode (ex: [image id=”123″]), and handle it at the moment of output… so the plugins can generate markup as needed.
