STEP 1. Edit the plugin.

From your admin area, goto plugins -> plugin editor. Select HD Quiz from the top right dropdown to being editing HD Quiz directly.

Open up the includes folder, then select functions.php to begin editing this file.

Now replace line 436 – $fields[$key]["value"] = wp_kses($v["value"], $allowed_html); with the following.

$fields[$key]["value"] = wp_kses_post($v["value"]);

Select the Update File button located underneath the editor to save.

STEP 2
We’ve now updated the plugin to allow just about any HTML in the question title field. This does not magically convert the field into a visual editor, but will allow us to add HTML to that field without it getting removed when you save.

So edit/add a new question, and add the following HTML tag to wherever you want the image to be placed in the title.

<img src = "####"/>

Replace #### with the full URL of the image. A “quick” way to get the URL of an image is to use the “Question Featured Image” feature to upload an image (you don’t need to set the image as a featured image, we are just using this as a quick way to upload images). When you upload an image, the right sidebar of the popup uploader will contain a section called “Copy Link” – this is the URL of the image you uploaded.

So a full example of a question would be:

This is a question that <img src = "https://wordpress.com/images/image.jpg"/> has an image in the middle of it.

This is what I meant when I said that it is possible to get the result you are looking for, it’s just not a very intuitive way of doing it 🙂

It looks like you did step 1 correct, so the issue must be step 2. That icon you see is an icon for an image tag that has an invalid source.
Can you show me the full text that you put into your question?

Yup. The issue is that the image you added does not exist…

Try going to the image directly: https://focanosestudos.com.br/wp-content/uploads/2020/05/Pretéritos-del-Indicativo-enem.jpg and you just get a 404 page not found error.

If you change the src link https://focanosestudos.com.br/wp-content/uploads/2020/05/Pretéritos-del-Indicativo-enem.jpg to one of a real image it will work

This would depend on your theme, but adding the following CSS has a good chance of working.

.hdq_question_heading img {
    display: block;
    margin: 0 auto;
}
