Hi Toledoh,
Were you only wanting to display a single image? In your getRecords function, you are including the uploads in your results so the following code should do the trick you're wanting. Note: I haven't tested it, so you might need to change some things to get it to work. If you want to display multiple images, you can just loop the $image variable and get every image attached to the record.
<?php foreach($researchSeries as $series => $items): ?>
<div class="row">
<div class="col">
<?php
$image = $items['images'];
if (!empty($images[0]['urlPath'])):
?>
<img src="<?php echo $images[0]['urlPath']; ?>">
<?php
endif;
?>
<h3><?php echo htmlencode($series) ?></h3></div>
</div>
<?php foreach ($items as $record): ?>.....<?php endforeach ?>
<?php endforeach ?>
