Works a treat! Thank you.
You're welcome.
The last thing I need to be able to do now is be able to keep the buttons - which select the galleries - lit, when scrolling through the images.
I notice that the highlighted button loses its highlighting not only when browsing through gallery images but also when clicking anywhere else on your page so it looks like the problem is with the CSS styling of your buttons rather than directly with the gallery itself.
Try adding the following CSS to your 'maincss.css' file (at the end of the 'slideNav' section):
#slideNav li a.selected {outline: none; border-color: #FFF; border-color: rgba(255,255,255,0.65); color: #FFFFFF; box-shadow: inset 0px 12px 8px rgba(255,255,255,.2); background-color: #487799;}... and add the following jQuery JavaScript to your web page (at the end of your existing $(document).ready(function() { ... }); section):
$('#slideNav li a').click(function() {
$('#slideNav li a').removeClass('selected');
$(this).addClass('selected');
});This jQuery JavaScript code adds a CSS class to the button which was most recently clicked (removing the class from all other buttons) and styles it accordingly (with the new CSS rule added to your 'maincss.css' file).
