Attitude | Tribulant Slideshow Gallery wanted on homepage only

Site: https://www.scotchology.com
Theme: Attitude

At one point in time, I created a slideshow and inserted it into my child theme Main Index Template (index.php), so that it only showed on the homepage. Somehow this has changed (updates?) and I’ve forgotten what I’d done to make the slideshow appear only on the homepage. Here is the code as it currently lies in my index.php file (1 is the code for my gallery):

<?php get_header(); ?>
<?php if (function_exists('slideshow')) { slideshow(true, "1", false, array())

; } ?>
<?php`

I’ve only noticed the change in the past month or two, so am assuming a recent update by WP, theme or plugin didn’t filter in correctly.

Any advice on whether it’s a matter of code correction or code placement? Please let me know if I need to provide any further information to be helpful. Thank you!
