Your PHP file can't read the ID from GET request unless the modal box is in fact admin/est_view.php However I think I understand what u'r trying to do,

STEP 1 :

create a file called admin/est_view.php that contain just the php script that will extract the data from DB and the foreach clause to form html response, and don't forget it needs to connect to the database.

Here's an example u can use or develop :

<?php
    try{
        $pdo = new PDO("mysql:host=localhost;dbname=demo", "root", "passwd");
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    } catch(PDOException $e){
        die("ERROR: Could not connect. " . $e->getMessage());
    }
    try{
        if(isset($_REQUEST["ID"])){
            $sql = "SELECT * FROM images_table WHERE :ID";
            $stmt = $pdo->prepare($sql);
            $term = $_REQUEST["ID"] . '%';
            $stmt->bindParam(":ID", $term);
            $stmt->execute();
            if($stmt->rowCount() > 0){
                while($row = $stmt->fetch()){
                    echo "<img src=\"" . $row["url"] . "\">";
                }
            }
        }  
    } catch(PDOException $e){
        die("ERROR: Could not able to execute $sql. " . $e->getMessage());
    }
    unset($stmt);
    unset($pdo);
?>

STEP 2 :

Now you can use your own JS :

$('#view_all_images_modal').on('show.bs.modal', function(e) {
    var est_id = $(e.relatedTarget).data('est-id');
    $.ajax({url:"admin/est_view.php?ID="+est_id,cache:false,success:function(result){
        $("#view_all_img_modal").html(result);
    }});

});
