it is likely that it is not a gd issue since gd does not support tiff. 
The tiff output is actually generated by MapServer I believe.  I would 
recommend against using tiff for now.

php_gd.dll was dropped in favour of php_gd2.dll in php 4.3.x, it is 
possible that some code still refers to php_gd.dll but you would get a 
different error message.  As far as Chameleon is concerned, they are API 
compatible so if you ever get messages saying that php was unable to 
load php_gd.dll, you can avoid it by copying php_gd2.dll and renaming 
the copy php_gd.dll :)  This is a hack, though, and the problem should 
be reported on the list so I can fix it.

Do you load mapscript automatically in your php.ini?  There is a section 
called extensions in there, if you list php_mapscript in that section, 
then the test does not need to load it and in fact loading it results in 
the error message that you see above.  To avoid this message, we 
typically use:

<?php
if (!extension_loaded( 'MapScript' ))
{
     dl( 'php_mapscript_4.0.1.dll' );
}
else
{
     echo 'MapScript loaded via php.ini<BR>';
}
phpinfo();
?>
