I'm sorry, I misunderstood that.
You should insert the slideshow's PHP snippet outside of the WordPress loop, which means placing it in your theme's 'index.php' file.
A good place to add the PHP snippet is probably after the line with '
<div id="content" role="main">' in your theme's 'index.php' file. Depending on wether or not you'd like to show it just on the home page, you can keep or remove the '
is_home()' check on the slideshow's PHP snippet.
It's possible to adapt the slideshow's stylesheet on the 'General Settings' page, then selecting the customized stylesheet as style setting on the slideshow's settings page. You can of course also add this space in the 'index.php' file itself.
