Hmm. I thought that I had a clever solution for you, but I don't. The
one that I came up with would probably be far more complex and inelegant
than you would ever want to use. If you were submitting your data to a
database or some kind of service, then it would work (I am thinking of
the PostToHost() function in the archives), but since you are trying to
set a session variable, you really need to refresh the page in the
process. This means that either using a form with POST data or the
querystring method that you mention above is really the best way to do
it.
If you used a form with POST data, you'd probably want to use radio
buttons or make a little listbox and a submit button, like:
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<select name="change">
<option value="inc">Increase Size</option>
<option value="dec">Decrease Size</option>
</select>
</form>
This would keep your querystring/URL free of extra data like
"page.php?change=inc".
