Verify url type

Question

I am trying to figure out ways to determine whether the url I am passing is an image or not. I have thought using getimagesize() to accomplish this task. But the main problem is, what if I want to check the image size of an encrypted image such as this url (https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTup5KSMveqkgrDKZR6p-0ANhPkJ7srbJOlKR78DUqqh85I_3MUrw)?

I am always getting this error:

Warning: getimagesize(): Unable to find the wrapper "https" - did you forget to enable it when you configured PHP? in C:\xampp\htdocs\series\index.php on line 4

Warning: getimagesize(https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTup5KSMveqkgrDKZR6p-0ANhPkJ7srbJOlKR78DUqqh85I_3MUrw): failed to open stream: No such file or directory in C:\xampp\htdocs\folder\index.php on line 4 0

If you cannot access the resource corresponding to the URL, you have no way of determining what type of content it corresponds to. — Oliver Charlesworth, Dec 29 '13 at 02:55

Couple of bits:

If you are running PHP5 (or could do) then you can use the HTTP Stream wrapper with the php.ini setting 'allow_url_fopen' set to on: This will allow you to do a 'straight forward' copy of any remote data to your server for processing.

e.g

<?php copy('https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTup5KSMveqkgrDKZR6p-0ANhPkJ7srbJOlKR78DUqqh85I_3MUrw', 'FileName.jpg'); ?>

Then you can do:

 <?php
    $size = getimagesize("FileName.jpg");
    echo $size;
    /*delete temp file*/
    unlink("FileName.jpg");
 ?>

Obviously not complete - but you can see the theory there
