The following PHP code will create image thumbnails on the fly . We are using PHP GD2 library. You will need to make sure that you have PHP with at least GD 2.0.1 enabled. Very simple script and very easy to customize.
<?php
header("Content-type: image/jpeg");
$image = $_GET['thumimg'];
$w = $_GET['w'];
$h = $_GET['h'];
if(!isset($w) && !isset($h)){
$w = 110; //default width if $w is not set
$h = 135; //default height if $h is not set
}
$x = @getimagesize($image);// get image size
$sw = $x[0];// width
$sh = $x[1];// height
$im = @ImageCreateFromJPEG ($image) or // Read JPEG Image
$im = false; // If image is not JPEG
if (!$im)
readfile($image);// return the actual message if error occurs.
else {
// Create the resized image destination
$thumb = @ImageCreateTrueColor ($w, $h);
// Copy from image source, resize it, and paste to image destination
@ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $sw, $sh);
// Output resized image
@ImageJPEG ($thumb);
}
?>
Save the above code as create_thumb.php
Generating thumbnails
Without specifying the width and height, let us say your image name is example.jpg then you can access this image by going to the URL below
http://www.<YOURWEBSITE>.com/create_thumb.php?thumimg=example.jpg
Add the above URL to IMG SRC tag
<img src="http://www.<YOURWEBSITE>.com/create_thumb.php?thumimg=example.jpg">
Add custom Width/Height
By specifying w and h in the query string along with the thumimg you can get the image size of your choice generated.
<img src="http://www.<YOURWEBSITE>.com/create_thumb.php?thumimg=example.jpg&w=100&h=100">
