Merging images

[Harley1979]

Hi,

 

Got this script below that resizes my images proportionately. For those images that are displayed portrait though I want to make them fit into a second image which is basically just a background pattern. How can I merge the two images?

 

Thanks

 

<?php

if($_SERVER['REQUEST_METHOD'] == 'POST'){

$caption = trim($_REQUEST['caption']);
if(empty($caption)){
	$err = true;
	$titleErrMsg = "You must give a title";
}

$title = $title.".jpg";

$section = $_REQUEST['section'];

$grayscale = $_REQUEST['grayscale'];

if($section == 0){
	$err = true;
	$sectionErrMsg = "You must choose a section to upload to";
}

$max_size = 8388608;

$size = $_FILES['imagefile']['size'];
$type = $_FILES['imagefile']['type'];
$imageFile = $_FILES['imagefile']['tmp_name'];

$src = imagecreatefromjpeg($imageFile);
list($origWidth, $origHeight) = getimagesize($imageFile);

if($type == "image/jpeg" || $type == "image/gif"){

Make a canvas just as big as the two images, and then place them side by side.  If you have not already, it might help to just run it through in Photoshop to make sure you are thinking correctly about it.

The required function is imagecopymerge()

Thanks guys,

 

But how do I place them side by side exactly?
