Create PNG using PHP

I have a MySQL database and would like to have a script in PHP that for each row that the script is looking at, would be able to take the data and arrange them on the page at the given dimension on a newly created PNG or JPEG.  One of the fields in the database would point to an image saved on the server that I would also like to appear on the new image file (as part of the new image, NOT showing the link to the image).

How can this be done?

Use the GD library:

<?php
// Create a 500x400 image
$im = imagecreate(500,400);

// Allocate some colors
$background_color = imagecolorallocate($im, 255, 255, 255); // White
$text_color = imagecolorallocate($im, 0, 0, 0); // Black

// Write some text at 20 pixels from the left, 10 pixels from the top
imagestring ($im, 1, 20, 10, "Some text", $text_color);

// Write some more text at 60 pixels from the left, 10 pixels from the top
imagestring ($im, 1, 60, 10, "Column 2", $text_color);

// Write some more text at 60 pixels from the left, 10 pixels from the top
imagestring ($im, 1, 60, 10, "Column 2", $text_color);

// Create a PNG file
imagepng($im, "newimage.png");

// Show in the browser
print "<img src='newimage.png'>";
?>

Yo ucan also use functions like imagecreatefrompng() and imagecopy() http://us.php.net/manual/en/function.imagecreatefrompng.php
http://us.php.net/manual/en/function.imagecopy.php

...to copy an existing image INTO the newimage.png image you are creating.

There's a LOT of ways to do this, but if you go to those links, you'll be able to  see all the different GD functions on the left-hand side. It's worth time to go through them and look at all the examples.

gr8gonzo - it appears that this will work, however, the solution to my problem is going to have to be a completely different route.  I do plan on using this function for a separate project I am working on, so THANK YOU!
