only the first image I am bringing from database is appearing - php

Question

I'm having a strange error, and I know Im posting a lot of code, but, Im really not understanding what Im doing wrong, so I decided to put all the code here related to my problem.
I also commented my code to be easily to understand context.
The problem is:
Im bringing my news information from database, and Im having a problem with images, only the image of the first post, which is the recent news, is appearing, the others dont appear.
However if I delete the code that I quoted like FROM HERE* **TO HERE*, images appear correctly.
Someone there realize why this is happening in this code excerpt that causes the images of my news do not appear?
<div id="content">

<?php
//first I read my news
$readNews = $pdo->prepare("SELECT * FROM news WHERE status = 1 ORDER BY date DESC LIMIT 0,4");
$readNews->execute();
//while exist news I want to read category of that news, and show news info in my article
while ($readNewsResult = $readNews->fetch(PDO::FETCH_ASSOC))
{
$readCat= $pdo->prepare("SELECT * FROM categories , news WHERE id_cat = ?");
$readCat->bindValue(1,$readNewsResult['category']);
$readCat->execute();
$resultReadCat = $readCat->fetch(PDO::FETCH_ASSOC);
//I show news info in my article
echo '<article class="loop-news">';
