getimagesize() function problem

Hi everybody of the PHP community,

I am using the php function "getimagesize()" to access the
width/height of an image
from the Web. This function should return false if image is not
available.

Most of the time the function works correctly, but in 2 or 3 cases I
have
a problem like, search is going on for minutes, and the function does
not return a
false return-code as it should if image is not available ?

If I enter the URL directly in the browser, the result is the same,
browser search for
Minutes and does not return any error.

Does anyone has experience with a similar problem, is there a timeout
that we can
Give to the function getimagesize() ?

Your comments are very welcome and best regards

Tks for your help

Shouldn't you first check to make sure the image exists?

$source = './images/some.gif';

file_exists($source)
? list($width, $height, $type, $attrib) = getimagesize($source)
: die('Unable to locate a required script: '.$source);

Tks for the info, but I think file_exists() cannot be used
with URL but only with regular files.

Thank you for the suggestion, but unfortunately I cannot use it
due to PHP version we use. I think "default_socket_timeout" is only
available from 4.3 on.
Tks any and best regards
