Text on Image Generation

Hey, and thanks in advance for anyone who can help me,

I was wonder how I have a text box, you type in your name and it prints in on a image

so lets say Ive got a template at "/template.png"

and I want to get my name on it "iNinja"

so i would like a PHP web application to have a text box, you type in iNinja and click the submit button and it saves the newly created image as "/image1.png" (if thats taken then "/image2.png" and so on...)

Thanks very much, Im starting out and need a place to work off.

This is what I did to create a Dynamic Sig.  I used XML, so it may not pertain to how you are doing it, but maybe it gives you some ideas.

This is actuall a file named mysig.jpg (notice the extension)

<?php
Header ('Content-type: image/jpeg');
Header('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
Header('Pragma: no-cache');


$current = "";
$pilot = '';

function start_tag($parser, $name, $attribs) {
   global $current;
   $current = $name;
}

function end_tag($parser, $name) {
global $current, $pilot;
}

function tag_contents($parser, $data) {
   global $current, $pilot;	 
   if ($current == "name") {$pilot[] = $data;}
   if ($current == "flights") {$pilot[] = $data;}
 if ($current == "miles") {$pilot[] = $data;}
   if ($current == "hours") {$pilot[] = $data;}

}

$parser = xml_parser_create();

xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($parser, "start_tag", "end_tag");
xml_set_character_data_handler($parser, "tag_contents");

$document = file_get_contents("pilots.xml","r") 
       or die("Error reading XML data.");

xml_parse($parser, $document);
xml_parser_free($parser);

echo $pilot[0];
echo $pilot[2];
