Add featured image to reviews list – WPCR_SHOW shortcode

Hi everyone.

So, on my website homepage, I am displaying the list of reviews received on different pages using the WPCR_SHOW shortcode.

This shortcode displays the review, the name of the page + permalink.

I want to show -> page reviewed + featured image of that page + review body.

I have gone through the plugin PHP code and found the declaration of the shortcode WPCR_SHOW and the generation of HTML using this:
$reviews_content = wpcr_Goatee::fill($this->options['templates']['frontend_review_holder'], $main_data);

Any way to show the featured image by modifying the PHP or the template?

Thanks!
