unfortunately you cannot do this without modifying some server files, eh... not sure which ones so don't ask me. There is a much easier way of tricking the user into thinking its a regular jpg image when it's really a php file. Make a new folder on your server called name.jpg and inside of it put your php file, but rename it to index.php. In many cases, on websites with dynamic images, you can add /index.php after the image and it will not result in a 404 error, because they use this.

Hi,

Thanks for your reply. but my problem is different. I want to make a watermark image while feching the orignal image from database

Hi!

This is a fab script...using it now on my site. However is there a way to position the watermark? Currently it displays in the centre, when preferably I would like the image to be displayed in the bottom right corner.

Does anyone know how to do this?

Thanks!
Matt

If I read and understand the script correctly, adjusting these start points in the script will affect the positioning of the watermark.
As an example, remove the "/2" in the width and height and see where the watermark displays on the image.
Try it and let us know if it works for you.

Hi jlhaslip,

Thanks for that, does the trick nicely! 1 and 1 puts it in the bottom right

Many thanks,
Matt

I use a pdf creation software named cutepdf to enhance my pdf output. Actually, i have the cutepdf paid version, might be the paid version which has all the nice features, but I think the basic, free version can 'stamp' pdf pages, too.

Great! can't wait to try this out! Thank you!

Hello people thank you for this script and as I made one that works for me for watermarking multiple picture on upload .

<?php

$watermarkPath = '/root_path_to_png_watermark/'.$watermark_name.'.png';
$target = '/root_path_to_where_upload_after_watermarking/'.$uploaded_picture_name;
$quality = "100";
$imagesource = '/root_path_to_where_upload_after_watermarking/'.$uploaded_picture_name;
$filetype = substr($imagesource,strlen($imagesource)-4,4);
$filetype = strtolower($filetype);
$watermarkType = substr($watermarkPath,strlen($watermarkPath)-4,4);
$watermarkType = strtolower($watermarkType);

if($filetype == ".gif")
$image = @imagecreatefromgif($imagesource);
else
if($filetype == ".jpg" || $filetype == "jpeg")
$image = @imagecreatefromjpeg($imagesource);
else
if($filetype == ".png")
$image = @imagecreatefrompng($imagesource);
else
die("a murit nu am scos imaginea");

if(!$image)
die("a murit nu avem imagine");

if($watermarkType == ".gif")
$watermark = @imagecreatefromgif($watermarkPath);
else
if($watermarkType == ".png")
$watermark = @imagecreatefrompng($watermarkPath);
else
die("a murit $watermark nu e");

if(!$watermark)
die("a murit lipsa watermark");

$imagewidth = imagesx($image);
$imageheight = imagesy($image);
$watermarkwidth = imagesx($watermark);
$watermarkheight = imagesy($watermark);
$startwidth = (($imagewidth - $watermarkwidth)/to);
$startheight = (($imageheight - $watermarkheight)/to);
imagecopy($image, $watermark, $startwidth, $startheight, 0, 0, $watermarkwidth, $watermarkheight);
imagejpeg($image,$target,$quality);
imagedestroy($image);
imagedestroy($watermark);
?>



Hope this works for you.
