ciao a tutti, sono nuovo qui...avrei una domanda da farvi.
Uso uno script per creare da determinate cartelle le thumb delle foto presenti in esse, impaginarle e creare i collegamenti..però vorrei modificarlo in modo tale che le foto si aprano nella stessa pagina e non in una pagina bianca..sapreste aiutarmi?
vi posto il codice
Codice PHP:
<?php
function thumbnalize($file, $sx=NULL, $sy=NULL, $filename=NULL) {
$info=@getimagesize($file);
switch($info[2]) {
case 1: //gif
$src=imagecreatefromgif($file);
break;
case 3: //png
$src=imagecreatefrompng($file);
break;
case 2: //jpg
default:
$src=imagecreatefromjpeg($file);
break;
}
if($src) {
$x=imagesx($src);
$y=imagesy($src);
if($x&&$y) {
if(!$sx && !$sy) $sy=150;
if(!$sx) $sx=$x*($sy/$y);
if(!$sy) $sy=$y*($sx/$x);
//if($sx>$x && $sy>$y) { $sx=$x; $sy=$y; }
$dst=@imagecreatetruecolor($sx,$sy);
if($dst) {
if(!$filename) {
if(!is_dir("thumbs")) mkdir("thumbs");
$filename="thumbs/$file";
}
imagecopyresampled($dst, $src, 0,0, 0,0, $sx,$sy, $x,$y);
@imagejpeg($dst, $filename, 50);
if(file_exists($filename)) {
chmod($filename, 0666);
return true;
}
}
}
}
return false;
}
class thumbs {
var $name,$orig,$thumb,$desc;

function get() {
if(!is_array($this->data)) return false;
