Found this forum post while looking for the same thing…
Got it working and thought it could help someone in the future…
When inserting into a custom theme template theme, use metadata like so:
<?php if ( function_exists( 'meteor_slideshow' ) ) { meteor_slideshow( "", "fx: 'scrollLeft', easing: 'easeInOutBack'" ); } ?>
Looks like you could do it with shortcode as well with something like this (haven’t tried this, but should be equivalent):
[meteor_slideshow metadata="fx: 'scrollLeft', easing: 'easeInOutBack'"]
This will kill the slideshow animation completely if you did not load an easing js file. Be sure you add something to your header that loads jquery easing… my phrase looks like this:
<script src="<?php bloginfo('template_url'); ?>/js/jquery.easing.1.3.js" type="text/javascript"></script>
Josh.. thanks for a great plugin!
