you can use gd library create image file binary code:

function binarytofile($binary_imagen, $width, $height, $new_name, $url_destiny) {      try{         //actual size         $info    = getimagesizefromstring($binary_imagen);         $old_width = $info[0];         $old_height = $info[1];          //new resource         $resource = imagecreatefromstring($binary_imagen);          $resource_copy  = imagecreatetruecolor($width, $height);          imagealphablending( $resource_copy , false );         imagesavealpha( $resource_copy , true );          imagecopyresampled($resource_copy, $resource, 0, 0, 0, 0,                    $width, $height,                     $old_width, $old_height);          $url = $url_destiny."/".$new_name".png";         $final = imagepng($resource_copy, $url, 9);          imagedestroy($resource);         imagedestroy($resource_copy);          return 1;      }catch (exception $e) {         return 0;     }  }
