Desired result: Loop an equivalent amount of modals as ID's within my database table1 whilst successfully looping images from table2 within those looped modals.
Current result: Loop one modal period whilst looping all images from table2 inside that one successful modal.
What do, and how?
<?php
include("dbconfig.php");
/*include("class.user.php");*/
$user_id = $_SESSION['user_session'];
$user_name = $_SESSION['user_name'];
$stmt = $DB_con->prepare("SELECT * FROM comment_imgs");
$stmt->execute();
while ($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
$id = $row['id'];
$date = $row['date'];
$comment = $row['comment'];
$project_id = $row['project_id'];
$display_id = $row['display_id'];
$user_name = $row['user_name'];
?>

Change the result variable $stmt in inner loop to something else, since you are overwriting the variable with which you are iterating.
$stmt = $DB_con->prepare("SELECT * FROM comment_imgs");
$stmt->execute();
$stmt = $DB_con->prepare("SELECT * FROM uploads");
$stmt->execute();
// the variable result is overwritten
