[PHP] [GD] Image errors

[Il pinguino volante]

Hi to all

I get a problem processing an image with GD libraries.

This is my function

   public function showPicture($id) {
   header('Content-type: image/jpeg');
   $mime = mime_content_type($this-updir.$id.'.png');
   $type = explode('/',$mime);
   $type = 'imagecreatefrom'.$type[1];
   $immagine = $tipo($this-updir.$id.'.png');
   imagejpeg($immagine,null,100);
   imagedestroy($immagine);
   }

If i commentize the header function i get a lot of strange simbols 
(such as the code of a jpeg image!) but no errors.
The result of this code is a blank page. In Firefox the title sets to 
picture.php (JPEG image) and if i right-click it and click on 
Proprieties i get 0px × 0px (resized as 315px × 19px).


P.S.: I get the same result when I write $immagine = 
imagecreatefromjpeg(...)


(Sorry for my english)

Thanks in advance,
Alfio.

[Fwd: [PHP] Sessions in databases]

[Il pinguino volante]

(There were some erroros in the previous email, I'm sorry)

Hi to all.

I have to realize an authentication system for a lot of users.

I heard that someone uses to store session states (?) into a database. I'd 
like to know how and, expecially, WHY to do it and what's would be better 
(considering that I CANNOT -d'oh!- edit the php.ini file).


Thanks in advance,
Alfio.
