So you want a link to the thread for the modification you are needing help with? How am I supposed to know which of the multiple gallery mods you are trying to work with.
Sure there is a similar thing in vB:
Code:
<vb:if condition="$_SERVER['REQUEST_METHOD'] != 'POST'">
But it all depends on where and what you are doing, if the variable is registered. That is why you need to ask in the modification thread.
