One thumbnail in photo album software

Q: I have one question concerning the visuallightbox gallery (I am using the business version for Mac): is it possible to enable the thumbnails and to start the slideshow only from one single image?

A: Yes, it is possible.
You can use the following parameter to hide thumbnails you don't want to display on the
style="display: none;"

for example:

<!-- Start BODY section id=1 -->
<div id="vlightbox1">
<a class="vlightbox1" href="data/images1/england.jpg" title="England"><img src="data/thumbnails1/england.jpg" alt="England"/></a>
<a class="vlightbox1" href="data/images1/france.jpg" title="France" style="display: none;"><img src="data/thumbnails1/france.jpg" alt="France"/></a>
<a class="vlightbox1" href="data/images1/german.jpg" title="Germany" style="display: none;"><img src="data/thumbnails1/german.jpg" alt="Germany"/></a>
<!-- End BODY section -->
