My front page includes an image slideshow by JJ NextGen Slider (Link). Therefore I am using PHP and
do_shortcode(). This is the full code:
<?php echo do_shortcode('[jj-ngg-jquery-slider html_id="about-slider" gallery="1" width="600" height ="355" resize="1" order="sortorder"]'); ?>
Unfortunately the slideshow is quite big and takes a long time to load, especially on mobile devices. Hence I wanted to implement a single button that the user must push to see the slideshow. Only if the button is pushed the slideshow may load.
