I need to be able to display secondary images outside the loop. More specifically, I need to be able to get the image URL(s) from outside the loop. Is that possible? the_post_thumbnail() only works inside the loop. I tried to use get_the_post_thumbnail() (it accepts a post ID as an argument so it can be used outside the loop) but the plugin doesn't work with get_the_post_thumbnail(). Any ideas?
