Hi vish,

while watching your code I found header(’Content-type: $image_type’); and header(’Content-type: image/jpeg’);.
You can only send one header at once, not two. Just use the last one to make sure everything gets done before you put the resized image on screen.

Then, if you need to resize gif and png you need another header, so implement a switch case i.e. to get the type and use the right functions for these types.

Hi
i want to resample an image to half its original size but there are not properly done
using the following code so please help me for solving the code :

0) {
$row = mysql_fetch_array ($result);
$percent = 0.5; //ex

$image_type = $row[”image_type”];
$image = $row[”image”];
$image_name = $row[”image_name”];

header(’Content-type: $image_type’);

// Get new dimensions
$width = imagesx($image);
$height = imagesx($image);

$new_width = $width * $percent;
$new_height = $height * $percent;

// Resample
$image_p = imagecreatetruecolor($new_width,$new_height);
$imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
// Output
header(’Content-type: image/jpeg’);
imagejpeg($image_p);

Regards ,
vish
