Merging images

[Michdd]

I've been looking for a tutorial on this, but I'm having a problem. I want to merge 2 different images from 2 URL's into 1 image.

Look up PHP's functions in the GD image library.

I tried this:

 

<?php
// Create image instances
$dest = imagecreatefrompng('http://tfg.game-host.org/bin/tfgcwp?Arcitex.png');
$src = imagecreatefrompng('http://eoinfo.no-ip.org:8080/playercards.php?name=arcitex&card=1.png');

// Copy and merge
imagecopymerge($dest, $src, 0, 0, 20, 20, 380, 128, 100);

// Output and free free from memory
header('Content-Type: image/png');
imagepng($dest);

imagedestroy($dest);
imagedestroy($src);
?>

 

It's just showing a broken image. It's not working..

I have no idea why, but i'm getting those error messages.

you sure you have the locations of your pictures correct, and are the permission set correctly(if required??)
