Answer 1

You already deleted the image entry in table, after that you try to get the same entry in DB. so, first you can delete the image from folder after that you can delete in the table.
<?php
include('global.php');
if($delete != "") {
$query = "SELECT * FROM images WHERE imageID='".$delete."'";
$result = mysql_query($query);
while ($delete = mysql_fetch_array($result)) {
$image = $delete['image'];
$file= '/.directory/'.$image;
unlink($file);
}
$query = "DELETE FROM images WHERE imageID='".$delete."'";
ExecuteQuery($query);
}
?>
Note:
Make sure your path $file= '/.directory/'.$image; is correct, I think it referring from root directory.

Funny. That's because you are first deleting the image id from the database and after that you are trying to get the ID of the previously deleted image (which no longer exists) and delete the file associated with it. Switch the code like this.
include('global.php');
if($delete != "")
{
//first delete the file
$query = "SELECT * FROM images WHERE imageID='".$delete."'";
$result = mysql_query($query);
while ($delete = mysql_fetch_array($result))
{
try
{
$image = $delete['image'];
$file= '/images/'.$image;
unlink($file);
} catch (Exception $e) {
}
}
// after that delete the id from the db of that image associated with the deleted file
$query = "DELETE FROM images WHERE imageID='".$delete."'";
ExecuteQuery($query);
}
UPDATE: I added a try catch

If you are deleting images, first you need to delete image and then delete in DB
