Bottom post ;)
$type = explode('/',$mime);
$type = 'imagecreatefrom'.$type[1];
$immagine = $tipo($this->updir.$id.'.png');
imagejpeg($immagine,null,100);
imagedestroy($immagine);
I'm not sure you understood what I meant. line 2 above $type is assigned
to the string 'imagecreatefrom'.$type[1];
Now I assume that was to be used later in some sort of eval() statement,
but its never called again, so the line really does nothing.
Thanks
