Set config parameter in your stage1 function.
$config['max_size'] = '1000000';$config['max_width'] = '1024000';$config['max_height'] = '768000';After then try it.
I'm not sure your server accept the ini "upload_max_filesize" property to be modified wit hphp script. By default it can't according to the documentation http://php.net/manual/fr/ini.core.php .
upload_max_filesize | "2M" | PHP_INI_PERDIR | PHP_INI_ALL pour PHP <= 4.2.3.
PHP_INI_PERDIR means that it must be writen in your ini file directly. If you have no controle over php.ini, you will not be able to override this property.
