So i was thinking to save them and display them, something like this:</p> <p><code>&lt;?php</p> <p>require_once 'ThumbLib.inc.php';</p> <p>$fileName = (isset($_GET['file'])) ? urldecode($_GET['file']) : null;</p> <p>if ($fileName === null || !file_exists($fileName))<br /> {<br /> echo "&lt;p&gt;imagine lipsa&lt;/p&gt;";<br /> }</p> <p>try<br /> {<br /> $thumb = PhpThumbFactory::create($fileName);<br /> }<br /> catch (Exception $e)<br /> {<br /> echo "&lt;p&gt;exception&lt;/p&gt;";<br /> }</p> <p>if(!file_exists('static/'.$fileName))<br /> {</p> <p>$thumb-&gt;adaptiveResize(170, 80);</p> <p>$thumb-&gt;save('static/'.$fileName);<br /> }<br /> $new = PhpThumbFactory::create('static/'.$fileName);</p> <p>if(file_exists('static/'.$fileName))<br /> {</p> <p>$new-&gt;show();<br /> }</p> <p>?&gt;</code></p> <p>So basically get the field name, save in static, and show it. Now i dont know if this uses resources each time i call it, to create a new thumb, or it takes it from static.</p> <p>Any suggestions? </p>
