cron not working with php+gd

[pushpen]

I'm trying to run the following php code along with gd library as a
cron job ,but cron is not generating any output.
When I run this code from my browser I get an image correctly.
Somebody please tell me what needs to be done to get an image via cron
job.
<?php
//Header("Content-type: image/png");
$height = 300;
$width = 300;
$im = ImageCreate($wi dth, $height);
$bck = ImageColorAlloc ate($im, 10,110,100);
$white = ImageColorAlloc ate($im, 255, 255, 255);
ImageFill($im, 0, 0, $bck);
ImageLine($im, 0, 0, $width, $height, $white);
for($i=0;$i<=29 9;$i=$i+10) {
ImageLine($im, 0, $i, $width, $height, $white); }
ImagePNG($im,"x .png");
?>

At a Guess I'd say you need to find a way of making cron generate an
email with the image as an attachment, but quite how you go about that I
really don't know. (cron usually only deals with text).

ImagePNG($im,"x .png");
?>

Does the user with this cron job have permission to create/overwrite
the file "x.png"?

And keep in mind that often the working directory is wherever the cronjob
started, NOT the directory of the script itself. You might want to try:

ImagePNG($im,di rname(__FILE__) ."/x.png");

wtf!?

cron is only responsible for initiating executables at given times. the only
time cron has anything to do with text is when it gives you vi to edit a
cron in response to 'cron -e'. even then, it's vi at work.
