from form to image

[nexx]

Is it possible to pass a variable from the form to GD script?

image created with GD would have to be embedded on the page after variable is passed.

<form name="form" method="post" action="somepage.php">
<input type="text" name="var" size="10">
<input name="go" type="submit" value="go">
</form>

This image link is on somepage.php
<img src="image.php"? <? $HTTP_POST_VARS['var']?>>

is that a correct way to pass $var to the link

Like this:

<img src="<? echo $_POST['var']; ?>">

pretty close,
on somepage.php, use:

<img src="image.php?<?php echo urlencode($_POST['var'])?>">

Thanx for your help guys.

Do I need to put anything in the image.php to get the 'var' processed by the script?

e.g $var = $_POST['var'];
