Hey Christian,
You may be able to replace the home blocks with a slideshow. The home page is made up of several repeating blocks that are like this:
<?php if(of_get_option('section_image_1', $single = true) != ""){ ?>
<style>
div#one .picture-block {
height: <?php echo of_get_option('section_image_height_1'); ?>px;
background-image: url(<?php echo of_get_option('section_image_1'); ?>);
}
</style>
<div class="picture-block"></div>
<div class="mobile-picture-block">
<img src="<?php echo of_get_option('section_image_1'); ?>" alt="" />
</div>
<?php } ?>
Essentially you would replace each one of those with the slider that you’d like to use in its place. Hopefully the slider has some sort of template tag you can use or at least a shortcode that you can use to add it in there.
In order to replace those blocks, it will have to be hard coded.
If you need me to do that, I can give you a quote on what it would cost to implement it for you.
