So, got the slideshow on my pages now but there's another problem. Seems to be theme-related since I've tried the exact same code on another theme and it works great. My theme is a mod of the stopdesign theme.
This is the code (I know it shows the same album on every page, it's just a test):
`
<?php $albumobject = new Album($_zp_gallery,"football"); ?>
<?php printSlideShow(false, false, $albumobject, "", 900, 360, true, true); ?>
<?php set_context(ZP_ZENPAGE_PAGE); ?>
<?php printPageContent();?>
`
And this on the head: <?php printSlideShowJS() ?>
In my theme the slideshow is displayed twice and it's just 2 static images. As I said, I've tried that code on another theme and the slideshow works perfectly.
Also, how can I show the controls to go to the previous/next image manually?
