Neither of these versions is supported any more.
If you think that the image generation is incorrect in a supported version, please can you let us
know, as well as providing the example image generated on your machine on a service like imgur.
For a lot of issues where images are generated incorrectly, the issue is dependent on your local
environment so providing the image you are seeing is required to allow the issue to be investigated.

Description:
------------
Image production with gdlib has changed between php
php-5.2.5 and php-5.3.3. Run the attached test script on both versions to see the
difference.
Test script:
---------------
<?php
$text = "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text.= "01234567890123456789\n";
$text.= "!@#$%^&*()_+=-][}{\\|'\";:/?.>,<";
$fontdir = './';
putenv('GDFONTPATH='.$fontdir);
$font = 'verdana.ttf';
$box = imagettfbbox ( 7.5 , 0 , $font , $text );
$width = abs($box[4] - $box[0]);
$height = abs($box[5] - $box[1]);
// Create the image
$im = imagecreatetruecolor($width, $height);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, $width, $height, $white);
// Add the text
imagettftext($im, 7.5, 0, 1, 10, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
// Set the content-type
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
