    Your line:

    echo '<img src="getImage.php?id=2">';

    will output this into your html page:

    <img src="getImage.php?id=2">

    Second, it will not load, execute and insert the result of getImage.php.

    Here's a solution:

    First page:

    <?php
include('getImage.php');
$id = $_GET['id'];
$img = getImage($id);
echo "<img src='$img' >";
?>

    getImage.php:

    <?php
include('confing.php');

function getImage($id){
    $sql="SELECT * FROM images WHERE id=$id ";
    $result=mysqli_query($connection,$sql);
    $row = mysqli_fetch_assoc($result);
    return $row['content'] ;
}
?>
