Hi Malte,
Thanks for your help! I had a look at zpfocus code, and looks like the way it is done there is using the following code to grab all the images:
<?php $x=0; while (next_image(true)):
if ($x>=1) { $css='noshow'; } else {$css='slideshowlink';} ?>
<a>" rel="slideshow" href="<?php echo htmlspecialchars(getFullImageURL());?>" title="<?php echo getBareImageTitle();?>"><?php echo gettext('Play Slideshow'); ?></a>
<?php $x=x+1; endwhile; ?>
Do you think something like this (with small adjustments as necessary) would also work for the zenpage theme?
Thanks!
Carlos
