[Help] dynamic-thumbnails-from-websites

I read this tutorial:
http://www.web-development-blog.com/archives/dynamic-thumbnails-from-websites/

but it not work with me:
http://www.MyDomain.com/thumb.php?url=webdigity.com

this the code in [thumb.php]:
<?php
function thumbnail($url) {
$client_id = 'sc010xxx'; // your client ID
$signature = '2007'; // the signature you entered @ girafa 
$concatenated = $signature.$url;
$MD5_Hash =    md5($concatenated);
$signature = substr($MD5_Hash, 16, 16);
$url = urlencode($url);
$str = 'http://scst.srv.girafa.com/srv/i?i=';
$str .= $client_id .'&r='. $url .'&s='. $signature;
return $str;
}
?>


Please tell me how to correct it,
and how to use the second script to cache the thumbnails on my own web server

There is no error! only blank screen!

Try this first :

ini_set('display_errors',true);?>

Do you get any error now?

Hello Nikolas,


I add that line, the same thing blank screen!

I'm using that [thumb.php] with other scripts, and I link with it by <img> code:

Code:

<img  src="/thumb.php?url=www.somedomain.com" width="160" height="120" />

the resulte is X image!

Can you tell us the url of your script?

http://www.xxxx.xxx/thumb.php

I have used the exact snippet you posted and it is working.

The use should be something like :

echo '<img  src="'.thumbnail('example.com').'" width="160" height="120" />'; ?>

Thank you!
the other thing if I want to cache the thumbnails on my own web server?

Check those functions :

file_get_contents
fopen
fwrite
fclose

If you need any assistance post in the forum

thank you
I think it's the last one 

Check those functions :

file_get_contents
fopen
fwrite
fclose

If you need any assistance post in the forum

many servers don't allow the use of fopen, and file_get_contents for security reasons so you may wish to look at curl instead if yoyur server is one of them, for example Dreamhosts prevents fopen

Right, you can check this cURL tutorial for more information on curl.

Hello again,

I think I have problem with $Signature code, I check both Signature resulte from the script and from Thumbnail URL Generator at Girafa.
they are not same code! for that I get X image!
for ex:
when I check msn.com in Thumbnail URL Generator the Signature will be:
4d9d906c622f00c6
but from this script [thumb.php]:
6daf94d3156e446d

I fix it, thank you again for help.
