Help GD

hello to all ... 
are now days that I think about how to do it, now you explain what 

I would basically call a img, below this picture to put a white stripe which says "hosted by". so if the img is large 400 * 400 should become 400 * 450 so that those in 50px + can enter text 

PHP Code: 

<? php 
$ im = imagecreatetruecolor (400, 200); 
$ middle = ceil ((400 - 200) / 2); 

$ image = imagecreatefromjpeg ( "tesserino.jpg"); 
list ($ width, $ height) = getimagesize ($ filename); 

$ color = imagecolorallocate ($ im, 190, 190, 190); 
$ colorShadow = imagecolorallocate ($ im, 190, 190, 190); 
$ pos = 1; 

$ font = 'adam_gorry_inline.otf'; 
$ FontSize = "10"; 
$ fontRotation = "0"; 

$ str = "Example of GD in PHP." 
/ * Top Level * / 
imagecopyresampled ($ im, $ image, 0, 0, 0, 0, 400, 200, $ width, $ height); 
ImageTTFText ($ im, $ FontSize, $ fontRotation, $ center, 195, $ color, $ font, $ str); 


/ / header ( "Content-Type: image / jpeg"); 
imagejpeg ($ im, "imagine.jpg", 100); 
imagedestroy ($ im); 

echo "<img src=\"imagine.jpg\">"; 
?> 

I have done something of this kind, but does not work, or I do not rimposta $ image .. you know me? 

Thank you
