I have to show you the way the bitmap font is loaded, to generate the png out of .nfo, .diz & txt files, BUT i need to know how to generate a bitmap font file (mine has no extension, it is an extension of a tiny script i found years ago on a google repository, so it has no extension, its just called 'nfo2pngfont'

here is how it's called in the nfo2png.php file-: 

// Load the Bitmap-Font
	$fnt = imageloadfont("nfo2pngfont");

Here is the nfo2png.php file: (it shows you can alter the font size, but only the [Generated by: NFOPic] is made larger od smaller by changing numbers 1 - 5 ??? it used to work, it's bizzre, not sure if someone who help do some code for me changed something, but DEFINARELY a BUG? 

<?php

function buildNFO($nfotext, $footer = "", $fg = "000000", $bg = "FFFFFF", $file_name = 'new_image', $path = 'uploads/' )
{
//	header("Content-Type: image/png");
//	header("Content-Disposition: inline; filename=\"" . $file_name . ".png\"");

	$nfotext = ( empty( $nfotext ) ? "Empty String submitted." : $nfotext );

	$nfo = explode("\n", $nfotext);

	// Load the Bitmap-Font
	$fnt = imageloadfont("nfo2pngfont");

	$nxo = array();
	$xmax = 0;

	$bigger_than_footer = false;
	// Reformat each line
	foreach( $nfo as $line )
	{
		$line = chop($line);
		if ( empty( $line ) )
		{
			array_push($nxo,$line);
			continue;
		}

		if ( strlen( $line ) > strlen( $footer ) )
		{
			$bigger_than_footer = true;
		}

		$fill = '';
		//add white space to each line until we have one bigger than the footer
		if ( !$bigger_than_footer )
		{
			$fill = str_repeat(" ", ( strlen( $footer ) - strlen( $line ) ) );
		}

		if($xmax < strlen($line.$fill)) $xmax = strlen($line.$fill);

		array_push($nxo,$line.$fill);
	}

	// Show footer
	if(strlen($footer))
	{
		array_push($nxo,"");
		$repeat_count = $xmax - strlen($footer)>>1;
		$repeat_count = ( $repeat_count >= 0 ? $repeat_count : 0 );

		//add whitespace to footer to push out to the middle

		//this line overrides the centering and only pushed it two from the left
		//remove this line to have it go back to the center
		//$repeat_count = 0;

		$fill = str_repeat(" ", $repeat_count );
		array_push($nxo,$fill.$footer);
	}

	// Linecount
	$ymax = count($nxo);

	// Set foreground color
	$color = array(0, 0, 0);
	if(strlen($fg) == 6)

		{
			$fnt = 1; //to use preloaded fonts, 1 - 5 only. 1 is tiny, 2 is decent, 3-5 are bolder/worse

Here is generate_image.php (this generates the PNG file)-: 

<?php
require_once 'include/db.php';
require_once 'nfo2png.php';

$file = explode( '.', $_FILES['user_file']['name'] );
$original_file_name = $_FILES['user_file']['name'];


$valid_file_types = array( 'txt', 'nfo', 'diz' );

$found = false;
foreach ( $valid_file_types AS $valid_file_type )
{
	if ( strtoupper( $file[count($file)-1] ) == strtoupper( $valid_file_type ) )
	{
		$found = true;
		break;
	}
}

if ( !$found )
{
    // echo '0|File must be one of the following types: ' . implode( ', ', $valid_file_types );
	die( '0|File must be one of the following types: ' . implode( ', ', $valid_file_types ) );
}


$content = file_get_contents( $_FILES['user_file']['tmp_name'] );

$file_name = 'image_' . str_replace( '.', '', microtime(true) );

buildNFONew(800, "20 50 20 50", $content, '[Generated by: NFOPic.com]', $_POST['fg_color'], $_POST['bg_color'], $file_name);

echo '1|'.$file_name . '.png|'.$original_file_name;

// if ( !is_local() )
if($conn)
{
	$sql = "INSERT INTO nfo_images (original_file_name, file_name, user_ip)
				VALUES (
					'" . mysqli_real_escape_string( $original_file_name ) . "',
					'" . mysqli_real_escape_string( $file_name.'.png' ) . "',
					'" . $_SERVER['REMOTE_ADDR'] . "'
					)
				";
	
// 	echo $sql;
// 	mysql_query( $sql );
    $conn->query( $sql );
}

and get_image.php (shows the link to the PNG image to hotlink or download, etc) -: 

<?php
require_once 'include/db.php';
$file_name = $_GET['f'];
if ( empty( $file_name ) || !file_exists( 'uploads/' . $file_name ))
{
	die( 'File not found...' );
}

$sql = "SELECT original_file_name FROM nfo_images WHERE file_name = '" . $file_name . "'";
$rs = mysql_query( $sql );
$file = mysql_fetch_assoc( $rs );

$original_file_name = explode( '.', $file['original_file_name'] );
//just get rid of the last, then put back together
array_pop( $original_file_name );
$original_file_name = implode( '.', $original_file_name );

header("Content-Type: image/png");
//start edit 10.07.2014 DrTech76, flow the direct image link through here to keep the actuall location unknown
if(!isset($_REQUEST["dl"]))
{//it's not a request through a direct link, so process as file download, as it was originally
	header("Content-Disposition: attachment; filename=\"" . $original_file_name . ".png\"");
}
//end edit 10.07.2014 DrTech76, flow the direct image link through here to keep the actuall location unknown
echo file_get_contents( 'uploads/' . $file_name );
?>

I hope someone can help figure this out, you can see live version of the site, to see the trouble, no matter what i change 1-5 to, only the 'footer' [GFenerated By: NFOPic] changes size..... so i'm thinking create a whole new monospaced ascii style bitmap font file like the one the original coder produced...... but not sure how. this is a community project going back years,, just re-launched it as i'm going back to learning php/mysql again after years in JS/jQuery/AJAX/CSS (UX Design & Illustration).... VERY GRATEFUL FOR ANNNNNY HELP! CAN HELP YOU OUT IN RETURN I HOPE, HAVE SOME GREAT RESOURCES, THOUGH LOVE HELP 4 HELP.... GREAT AT ILLUSTRATION!!!! LOGOS ETC.
