++Node Type Check

For block visibility it is often desired to show blocks on nodes of certain
types.  The util_check_node_type function does just that.  You can now easily
get this functionality using a block visibility test like:

<?php
return util_check_nodetype(array('blog','image'));
?>

Placing that code in the "Page specific visibility settings" and selecting
"Show if the following PHP code returns TRUE (PHP-mode, experts only)." will
show the block on all pages of type blog or image.
