Thumbnailing with GD!!

[Fatboy]

Hi.

I have downloaded a thumbnailer script and it works fine with one picture.

Now, I have a directory full of pictures that I want thumbnailing and displayed.

When I do a recursive search through the directory it displays the first image as a thumbnail and that is it.

I guess this is because as the thumbnailer script displays the first image it sends the 'header(Content-type....blah de blah)" so when the second on comes to print the headers have already been sent and errors.

So how can i go through a directory of pictures and send thumbnails of them all to the screen?

Cheers all - been trying to figure this one out for a few hours now!!!

//edit: this is the code i am using.

The bit to display the image from the thumbnailer:

function show()
        {
                //show thumb
                @Header("Content-Type: image/".$this->img["format"]);

            /* change ImageCreateTrueColor to ImageCreate if your GD not supported ImageCreateTrueColor function*/
            $this->img["des"] = ImageCreateTrueColor($this->img["lebar_thumb"],$this->img["tinggi_thumb"]);
                @imagecopyresized ($this->img["des"], $this->img["src"], 0, 0, 0, 0, $this->img["lebar_thumb"], $this->img["tinggi_thumb"], $this->img["lebar"], $this->img["tinggi"]);

            if ($this->img["format"]=="JPG" || $this->img["format"]=="JPEG") {
                    //JPEG
                    imageJPEG($this->img["des"],"",$this->img["quality"]);
            } elseif ($this->img["format"]=="PNG") {
                    //PNG
                    imagePNG($this->img["des"]);
            } elseif ($this->img["format"]=="GIF") {
                    //GIF
                    imageGIF($this->img["des"]);
            } elseif ($this->img["format"]=="WBMP") {
                    //WBMP
                    imageWBMP($this->img["des"]);
            }
    }

nd my recursive thing:

<?
include("thumb.php");

$dir_name = "pics1/";
$dir = opendir($dir_name);

while ($file_name = readdir($dir))
{
$picture = $dir_name.$file_name;
 if (($file_name != ".") && ($file_name != ".."))
 {
    $thumb=new thumbnail($picture);
    $thumb->size_auto(100);
    $thumb->show();
 }
}
closedir($dir);
?>

I would modify the script slightly. Instead of using header() to display the image, I would just use echo to output the html code to view the image. That way, no header info needs to be sent.
