I have created (adapted) the follow function:
function imageresize($new_width, $new_height, $filename) {
// Content type
header('Content-type: image/jpeg');
// Get new dimensions
list($width, $height) = getimagesize($filename);
// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width,
$new_height, $width, $height);
// Output
imagejpeg($image_p, null, 100);
}
The idea is it takes a image and resizes it at server end so that you
dont have to download a massive image. And it works.
That is as long as that function is the only think you doing.
For example if I have a page with the following in it:
<?php
require_once('../includes/functions.php');
imageresize('100', '75', 'pages/1.jpg');
?>
I get my image resized. (functions.php is where all my fuctions are
stored) However if I place anything after the imageresize it doesnt
show that. Eg echo"hello'; does nothing. If anything goes before it the
whole page doesnt work.
Any ideas why this is happening and how I can work around it?
You can display either image or html, not both. You must do:
<img src="thumb.php">
thumb.php contains the code to output the thumbnail
