cia kai prasai, tai niekas nereaguoja?
cia yra gfx.php failas, kuriame ir kuriamas watermarkas

kurioj vietoj ir ka padaryti, kad jis butu be fono ir nuotraukos viduryje, o ne kampe?

Ne nu bet tu tai kurmis, skaityk kas parašyta tavo kode gi:
//location of the watermark on the source image
$size = getimagesize($source_photo);
$dest_x = ($size[0] - $watermark_width) - 5;
$dest_y = ($size[1] - $watermark_height) - 5;
Su anglų visiškas abelis matyt. Keisk į
//location of the watermark on the source image
$size = getimagesize($source_photo);
$dest_x = ($size[0] - $watermark_width) - 300;
$dest_y = ($size[1] - $watermark_height) - 250;
Jei foto standartiškai ~ 600x500 dydžio.

Labai abejoju ar išeitų, na bet teoriškai įmanoma, kadangi įmanoma išgauti foto plotį/aukštį, tada reiktų daryti taip:
//location of the watermark on the source image
$size = getimagesize($source_photo);
$dest_x = (($size[0] - $watermark_width)/2);
$dest_y = (($size[1] - $watermark_height)/2);
