Answer 1

I think your delete query is wrong
if(isset($_GET['img_id'] , $_GET['img'])){
$id=$_GET['img_id'];
$img=$_GET['img'];
$query="delete from images where id='$id' and image='$id'";
}
$query="delete from images where id='$id' and image='$img'";
In this query you check Id and Image field with same $id variable

Answer 2

try this :
<?php
if (isset($_FILES['image']['name'])) {
$name = $_FILES['image']['name'];
$tmpname1 = $_FILES['image']['tmp_name'];
$exten = explode(".", $_FILES['image']['name']);
$exten = $exten[1];
if ($exten != '') {
$image_name = "img" . time() . "." . $exten;
}
move_uploaded_file($tmpname1, FCPATH . 'assets/admin/uploads/' . $image_name);
$query = "insert into images(id,img_name) values('your_id',' $image_name')";
mysqli_query($con, $query);
//see your code
/*
$id=$_GET['img_id'];
$img=$_GET['img'];
$query="delete from images where id='$id' and image='$id'";
*/
you pass the same id value for image. you should try this-
$query="delete from images where id='$id' and image='$img'";
}
