А всего-то надо внести небольшие изменения в файл …/includes/functions_upload.php вашего форума.
1. Найдите в нем следующие строки:
phpbb_chmod($this->destination_file, $chmod);
}
Добавьте после них: $this->resize();
2. Найдите далее:
return true;
}
Добавьте после:
Код: Выделить всё
function resize(){
global $config;
if (!empty($config['img_max_width']) && !empty($config['img_max_height'])){
$max_width = $config['img_max_width'];
$max_height = $config['img_max_height'];
}else{
$max_width = 800;
$max_height = 600;
}
if (!empty($max_width) && !empty($max_height)){
$filename = $this->destination_file;
if ($image_info = @getimagesize($filename)){

}
