Best way to check for [gallery] shortcode in plugin overriding it

Here's a sample of code from the plugin I'm using that turns [gallery] into a slideshow:

    // Check for [gallery] shortcode

    function have_gallery( $posts ) {

        if ( empty( $posts ) || $this->has_gallery )

            return $posts;

    

        foreach ( $posts as $post ) {

            $pos = strstr( $post->post_content, '[gallery' );

            if ( false !== $pos && $pos >= 0 ) {

                $this->has_gallery = true;

                break;

            }

        }

    

        if ( $this->has_gallery ) 

                $this->enqueue_assets();

                    

        return $posts;

        

    }


The plugin/code works fine if the [gallery] shortcode is within the page/post content (WYSIWYG / HTML editor) area, but it doesn't work if do_shortcode('[gallery]'); is used in a page template... AND [gallery] is not in the content area.

Said another way, I have to type [gallery] into the WYSIWYG area in order for do_shortcode('[gallery]'); to work... EVEN THOUGH the content isn't displayed on the page/post/CPT template.

Is there a way to edit/rewrite the code above to be able to play nice with do_shortcode WITHOUT having to do that little trick of entering [gallery] into the WYSIWYG area?

FYI: Related question here: http://wordpress.stackexchange.com/questions/70649/wp-insert-post-data-for-cpt

Thank you.

      I upload images to create the gallery but then want to use it in a page template. Like I said, all works perfectly if I put [gallery] in the content area even though I don't display it at all on the page.
