How-To generate Full URL Thumbnail?

[Giorgi]

So in link_summary.tpl I tried to insert:

<img src="http://www.artviper.net/screenshots/screener.php?url={$url}&amp;sdx=1024&amp;sdy=768&amp;w=128&amp;h=96&amp;&amp;q=90" 
style="float:left;margin-left:62px;margin-right:16px;margin-top:2px;margin-bottom:60px;border:1px 
solid #D8B93B;" alt="{$url_short}" height="96" width="128" />

but $url variable does not return full url of submitted story, I guess its just story url.

So what should I do if I want to display full url thumbnails? (not only root screens)

Thank you

solved that, in case anybody needs to know, I used

$enc_url

variable instead of $url
