Captcha font

[Zaper Gallis]

Ok, I'm writing a captcha script for my site and i have it working and doing most of what i want. Here's what i have:

<?php session_start(); 	//imagecreatefrompng :: create a new image from file or URL	$img = rand(1, 4);		if ($img == 1)	{		$img = imagecreatefrompng('captchaimage1.png');	}	else if ($img == 2)	{		$img = imagecreatefrompng('captchaimage2.png');	}	else if ($img == 3)	{		$img = imagecreatefrompng('captchaimage3.png');	}	else if ($img == 4)	{		$img = imagecreatefrompng('captchaimage4.png');	}		//displaying the random text on the captcha 	$word1 = rand(1, 10);	if ( $word1 == 1)	{		$word1 = "The" . rand(1, 9) . "rn" . rand(1, 9);	}	if ( $word1 == 2)	{		$word1 = "Sh" . rand(1, 9) . "uth" . rand(1, 9);	}	if ( $word1 == 3)	{		$word1 = "Puta" . rand(1, 9) . "h" . rand(1, 9);	}	if ( $word1 == 4)	{		$word1 = "r" . rand(1, 9) . "ies" . rand(1, 9);	}	if ( $word1 == 5)	{		$word1 = "ri" . rand(1, 9) . "tys" . rand(1, 9);	}	if ( $word1 == 6)	{		$word1 = "cro" . rand(1, 9) . "wle" . rand(1, 9);	}	if ( $word1 == 7)	{		$word1 = "ri" . rand(1, 9) . "tys" . rand(1, 9);	}	if ( $word1 == 8)	{		$word1 = "g" . rand(1, 9) . "res" . rand(1, 9);	}	if ( $word1 == 9)	{		$word1 = "si" . rand(1, 9) . "ons" . rand(1, 9);	}	if ( $word1 == 10)	{		$word1 = "hi" . rand(1, 9) . "zing" . rand(1, 9);	}		$word2 = rand(1, 10);	if ( $word2 == 1)	{		$word2 = "The" . rand(1, 9) . "rn" . rand(1, 9);	}	if ( $word2 == 2)	{		$word2 = "Sh" . rand(1, 9) . "uth" . rand(1, 9);	}	if ( $word2 == 3)	{		$word2 = "Puta" . rand(1, 9) . "h" . rand(1, 9);	}	if ( $word2 == 4)	{		$word2 = "r" . rand(1, 9) . "ies" . rand(1, 9);	}	if ( $word2 == 5)	{		$word2 = "ri" . rand(1, 9) . "tys" . rand(1, 9);	}	if ( $word2 == 6)	{		$word2 = "cro" . rand(1, 9) . "wle" . rand(1, 9);	}	if ( $word2 == 7)	{		$word2 = "ri" . rand(1, 9) . "tys" . rand(1, 9);	}	if ( $word2 == 8)	{		$word2 = "g" . rand(1, 9) . "res" . rand(1, 9);	}	if ( $word2 == 9)	{		$word2 = "si" . rand(1, 9) . "ons" . rand(1, 9);	}	if ( $word2 == 10)	{		$word2 = "hi" . rand(1, 9) . "zing" . rand(1, 9);	}		$key = $word1 . " " . $word2;		$_SESSION['check'] = ($key);		//The function imagecolorallocate creates a color using RGB (red,green,blue) format.	$textcolor = imagecolorallocate($img, rand(0, 199), 0, 0);	$line = imagecolorallocate($img,0,0,0);	$lineselect1= rand(1, 2);	$lineselect2= rand(1, 2);	$lineselect3= rand(1, 2);	$lineselect3= rand(1, 2);		if ($lineselect1== 1)	{	imageline($img,rand(0, 200),0,rand(10, 200),75,$line);	}	else	{	imageline($img,0,rand(0, 200),255,rand(10, 200),$line);	}	if ($lineselect2== 1)	{	imageline($img,rand(0, 200),0,rand(10, 200),75,$line);	}	else	{	imageline($img,0,rand(10, 255),255,rand(10, 200),$line);	}	if ($lineselect3== 1)	{	imageline($img,rand(0, 200),0,rand(10, 200),75,$line);	}	else	{	imageline($img,0,rand(10, 255),255,rand(10, 200),$line);	}	if ($lineselect4== 1)	{	imageline($img,rand(0, 200),0,rand(10, 200),75,$line);	}	else	{	imageline($img,0,rand(10, 255),255,rand(10, 200),$line);	}		imagestring($img, 10, 8, 3, $key, $textcolor);	header ("Content-type: image/png"); imagepng($img); ?>

And a live demo is on my site at: http://www.webmasterseverything.com/test/What i need now is to make the text bigger and easier for humans to read (a must), and I'd like to be able distort the text like most captcha's (Not so important right now). I can't find anything on Google for this that doesn't expect me to be using a pre-programed system. Can some one explain how to do this, or give me a link explaining it?And one final thing, I heard of some kind of something called "TTF font", but can't find a clear explanation of what it is or how to use it in a captcha. does any one have a good explanation of it?Thanks for the help.

TTF is one of the font formats, it's TrueType. There are several functions which use those fonts with images:http://www.php.net/manual/en/function.imagettftext.php

OK, one more thing came up. Does any one know were i can find a TTF that i can use for this freely and redistribute without braking any copyright laws?Edit: Never mind, i found a place, thanks anyways.

Edit: Ouch, it looks like this thread was solved already and I hadn't seen.Some, not all, of the fonts on http://www.dafont.com/ are free to use. Check the information of a font before using it.
