gd paths and fonts

[bleak26]

HI i would like to use gd to edit an image and add some text,i am using PHP Version 4.3.8 and i am using the following code.

<?php
$im = imagecreatefrompng('bars/title_test.png');
putenv('GDFONTPATH=usr/www/users/mimi7818/fonts/');
$fontname="HIROSHT";
$texttobeadded = "test text for button";
$x = 10;
$y = 100;
$color = imagecolorallocate ($im, 249,255,0);
imagettftext ($im,50,0,$x,$y,$color,arial,$texttobeadded);
header ('content-type: image/png');
imagepng ($im);
?>

i get this error
Warning:# imagettftext(): Could not find/open font in /usr/www/users/mimi7818/add_text_to_bar_image.php on line 10

1.please could you tell me what is wrong ?
2.is the gdfontpath absolute or relative ? if so how do i find out the correct path ?
3.do i need to include .ttf in my font name ?
4.can i include a path in my font name ?

i use gd very much in a windows environment but i've never needed to set an environment var...

aanyway if you say this is the way to do it i'll believe you, but still relative or absolute, "GDFONTPATH=usr/...." IS a relative path, so try /usr/...

but i dont think this is necessary, do a
$dir="/usr/path/";
$font="hirosht";

and

do imagettftext(..... , $dir.$font,...)

but now i see your problem anyway, you have a "arial" mixed in your arguments...
