Okay, now we are getting somewhere!
The easiest way to meet the unique filename requirement is to name
each file after its letter:
a.png
b.png
c.png
Of course, they only need to APPEAR that way to the browser and
Javascript.
In reality, you may not actually have a file named "a.png" at all.
For example, if your HTML is like this:
<img src="/drawchar.php/a.png" />
And you have a PHP script drawchar.php like this:
<?php
//EG: $path_info will be "/a.png",
//because that is what is in tha URL AFTER the PHP script name
$path_info = $_SERVER['PATH_INFO'];
//get JUST the one letter
$char = substr($path_info, 1, 1);
//Create the image:
$image = imagecreatetruecolor(40, 10);
//Boring colors, but works for now:
$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
//make the background white:
imagefilledrectangle($image, 0, 0, 39, 9, $white);
//draw the character:
$font = 3; //Fonts can be 1 through 5
$x = 2;
$y = 38;
imagechar($image, $font, $x, $y, $char, $black);
//Find out how big the image is:
ob_start();
imagepng($image);
$image_raw = ob_get_contents();
ob_end_clean();
$image_length = strlen($image_raw);
//Send suitable headers:
header("Content-type: image/png");
header("Content-length: $image_length");
//Send the data:
echo $image_raw;
?>
You can now just pass the word 'dissatisfaction' around, and use PHP
or JavaScript to output individual images.
I'll do it in PHP:
<?php
$word = 'dissatisfaction';
for ($i = 0, $len = strlen($word); $i < $len; $i++){
$char = $word[$i]; //or use substr if you like
echo "<img src=\"/drawchar.php/$char.png\" />";
}
?>
I haven't run this code to test it, so there might be a typo, but it's
going to be MUCH easier to maintain than what you've got going...
