This applies at least to version 1.2. If your hosting environment is not setup to allow for php short tags; the admin for this plugin will not show any FX. Alter line 106 of wp-content/plugins/ycyclista/ycyclista_admin.php and exchange the php short tag with the full tag:
Immediately you will see the FX in the admin and the slideshow gallery will work great! Excellent plugin! Easily uses the pre-existant WordPress image functions!
Found all kinds of great results about my favorite band while searching for info on this issue :) 'ycyclista no fx'
Hope this helps someone else :)
