Help merging two images

[Krisando]

Basically I am merging two images, the image merging with it is larger then the source image.

I'm also getting a black line at the top. =\

 

I'm not quite sure how to merge images so any help would be much appreciated.

<?PHP
   $dest = imagecreatefrompng('http://f.imagehost.org/0548/online.png');
   $src = imagecreatefrompng('http://f.imagehost.org/0009/stats.png');

   imagecopymerge($dest, $src, 0, 10, 0, 0, 170, 108, 75);

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

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

To see this script in action http://frozenstarfire.com/read.php.

This is for non-profit purposes and has nothing to do with the frozenstarfire.com website, just using as webspace.

 

Thanks guys, any help understanding this would be great!

It wont let me edit the post so new code:

<?PHP
   $dest = ImageCreate(170, 130);
   $status = imagecreatefrompng('online.png');
   $stats = imagecreatefrompng('stats.png');

   imagecopy($dest, $status, 0, 0, 0, 0, 170, 30);
   imagecopy($dest, $stats, 1, 21, 1, 0, 168, 108);

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

   imagedestroy($dest);
   imagedestroy($status);
   imagedestroy($stats);
   //
?>

I have managed to merge two images of different sizes, although it looks ratough it looks rather distorted. The black line has gone when I replaced "imagecopymerge()" with "imagecopy()", likely an alpha channel bug.

 

I have a strange white line on the top of the bottom image attached, the thick white like you can see overlapping in http://frozenstarfire.com/read.php, I have no idea what is causing this. At the same time I am trying to write text ontop some how. Quite stuck.

Okay, I had to make the bottom part a gif to show transparency .

<?PHP
   $dest = ImageCreate(170, 130);
   $status = imagecreatefrompng('online.png');
   $stats = imagecreatefromgif('stats.gif');

   imagecopy($dest, $status, 0, 0, 0, 0, 170, 30);
   imagecopy($dest, $stats, 1, 21, 1, 0, 168, 108);

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

   imagedestroy($dest);
   imagedestroy($status);
   imagedestroy($stats);
   //

I'm not sure how to link "imagecreatefrompng('online.png');" the 'online.php' part to a url, so that would be a great help.

I also have no idea how to draw text onto the image, like an overlay. =\

 

I may have to somehow merge a text image onto this image? Or draw text straight on.
