[Plugin: Thumbnail For Excerpts] How to show the thumbs on the footer of posts?

Hi everyone,
I’m using the Thumbs for Excerpts to generate thumbnails of my posts, what it was designed for. I searched for similar and found this one the most appropriate for my case.

The plugin worked perfectly, but I’m trying to make an adjustment to display the thumbs for other posts at the bottom of each one. More clearly, I want to do something similar to this reference:
https://www.pposti.com/#1090504/Granta, when viewing a post, the thumbs of the others are at the bottom of it.

I tried to use two plugins jointly, those that loads similar posts at the bottom, but without success. I also tried to edit the code, specifically the single.php, but I’m not a PHP pro, and I don’t know to use the_excerpts() properly (and don’t know if that would be enough to make this work).

If anyone has an easier solution, or a hint how to display the thumbs at the bottom of posts, just like the reference, I’ll thank you very much.

Thanks,
Caio.
