You can use TTF fonts, im just trying to work out how you change the size :(#
For Example:
PHP Code:
$font = imageloadfont("./fonts/yourfont.ttf");
imagestring ($image, 12, 0, $textheight, $str1, $font,$color);
imagestring ($image, 12, 0, $textheight + 13, $str2, $font, $color);
imagestring ($image, 12, 0, $textheight + 26, $str3, $font,$color);
imagestring ($image, 12, 0, $textheight + 42, $str6, $font,$color);
imagestring ($image, 12, 0, $textheight + 55, $str7, $font,$color);
Thenupload your font to a folder called fonts in your FTP :)
