Heya, Sejal.

Have a look at PHP's GD functions (http://php.net/gd).

Thanks for your reply.......
But i don't want that gd functions.I want the script from which i can download image of variable sizes.

I think if you want that script you're going to have to bite the bullet and write it!

You could create several links in your page:
[HTML]<a href="image.php ?height=200&wid th=400">400 x 200</a>
<a href="image.php ?height=300&wid th=600">600 x 700</a>
<a href="image.php ?height=400&wid th=800">800 x 400</a>[/HTML]
And then you need a bad ass script that takes the original image out of the database and uses the height and width variables ($_GET['height'] and $_GET['width']) to create a smaller version of it using the GD functions.

Here's a start. You'll need to fill in the gaps and refer to the GD functions :
[PHP]$orig_image = imagecreatefrom jpeg('place where the original image is saved');
$new_image = imagecreatetrue color($_GET['width'], $_GET['height']);
//possibly imagecoloralloc ate(); stuff here
//now copy $orig_image into $new_image but at reduced size:
imagecopyresamp led();//that will need various parameters

header('Content-Type: image/jpeg');
imagejpeg($img) ;
imagedestroy($i mg);[/PHP]

Oops, last 2 lines should have been:[PHP]imagejpeg($new_ image);
imagedestroy($n ew_image);[/PHP]
