Update:
After a day of this, I’ve managed to get the lightbox working for each Album listed on the one page using the code below which I’ve posted so someone else might benefit in the same position.
-Still one outstanding problem though - Lightbox is counting all images regardless of which album they are in so launching the first albums lightbox gives 1 of 17 images (first album actually contains 9 images) launching the second album lightbox gives 9 of 17 (contains 8 actual images)
<ul>
<% control Albums %>
<li>
<figure>
<% if CoverImage %>
<% control FormattedCoverImage %>
<img src="$URL" alt="Image of $AlbumName website" />
<% end_control %>
<% else %>
<span class="no-image"></span>
<% end_if %>
<figcaption>
<h3>$AlbumName</h3>
<p> $Description</p>
<p class="further-reading">
<% control GalleryItems %>
<% if First %>
<a rel="lightbox" class="lightbox" title="$Caption.EscapeXML" href="$Large.URL">View Slideshow »»</a>
<% else %>
<a rel="lightbox" class="lightbox" title="$Caption.EscapeXML" href="$Large.URL"></a>
<% end_if %>
<% end_control %>
</p>
</figcaption>
</figure>
</li>
<% end_control %>
</ul>
