   Hi guys,

   I've got his code that I use a lot.

   $images =&get_children( 'post_type=attachment&post_mime_type=image&post_parent=' . get_the_id() );

   My question is what does the ampersand (bolded) do in that case?

   No, that won't answer my question, but thanks anyway. I read that before I came to the forums for help.

   This is the assign by reference operator; this way you get a real reference (or alias) as opposed to a copy of a reference; this doesn't matter so much these days, assuming you're using PHP5.
