Having Trouble with the 'else_if' coding for home page slideshow

I sure appreciate some help with some code. I’m attempting to use ‘else_if’. I have a slideshow that I only want showing on the home page and not when someone clicks “older entries” on the second page and third and so on.

Here my code <?php include (ABSPATH . '/wp-content/plugins/featured-content-gallery/gallery.php'); ?>

Everything I have tried thus far pulled up an error. Any help would be sweet.

Thanks,
