Image manipulation and PHP

I have 2 images:

image1.jpg (650 x 300 px)
image2.jpg (10 x 10 px)

Basically I want PHP to place image2.jpg over the top of image1.jpg, in a certain place (e.g. 100w, 100h), then save the whole thing as a JPEG.

Any ideas how I can about doing this?

Many thanks.

http://us2.php.net/manual/en/function.imagecopymerge.php should get you started.  Can you please post the code you have so far?  Thanks, ~Ray

I haven't any code just yet. Is it possible to add some text over the top of the second image, and then save the whole thing as one image?

Yes, you can stack text or other images on top of a background image.  That function above does it for image stacking.  The imagestring() or imagestringup() functions can do it for text.  Then you can create the file with imagejpeg() and you're done.  There is a lot to be found in the GD functions for PHP.

Have a quick read of the functions on this page, and you will find almost everything you could desire!

Thanks for the points.  Here is a little code snippet that shows what I do to create a little image of a "captcha" number string.  If you look up the functions in the top part, you will get the gist of it quickly.

Cheers, ~Ray
<?php // CAPTCHA_NUMBER.PHP GENERATES A PICTURE OF A NUMBER
 $data	= base64_decode($_GET['dt']);
 $im	= imagecreate(46,13);
 $bg	= imagecolorallocate($im, 255,255,255);
 $gray	= imagecolorallocate($im, 188,188,188);
 $text	= imagecolorallocate($im, 178,34,34);  // firebrick
 imagestring($im,5,4,0,$data,$text);
 imageline($im,4,12,38,0,$gray);
 imagepng($im);
 imagedestroy($im);
?>
 
 
 
 
 
 
<html> <!-- GOES IN THE FORM SCRIPT -->
Type
<img style="display:inline;" src=captcha_number.php?dt=<?php $x = mt_rand(1000,10000); echo base64_encode($x);?> />
here:
<input type=hidden name='_newMd5' value="<?=md5($x)?>" />
&nbsp;
<input name="_newCode" type="text" maxlength="64" size="6" autocomplete="off" />
 
 
 
 
 
 
 
<?php // GOES IN THE ACTION SCRIPT
$newCode	= $_POST["_newCode"];
$newMd5		= $_POST["_newMd5"];
$newCode	= md5($newCode);
if ($newCode != $newMd5)
{
	die('Security code number did not match');
}
