flu on "printRandomImages and dynamic album + pagination error"

Hi guys,
I use :
Zenphoto 1.4.6
Theme : zpskeleton (the adapted one for 1.4.6 by Fretzl in the Github unsupported directory)
PHP : 5.3.28
MySQL : 5.1.67
rewrite mod : on

1. Using this theme, I've noticed that the pagination works fine if the gallery.php is on the home page (http://www.site.com/page/1, http://www.site.com/page/2, http://www.site.com/page/3, etc.) but it gives 404 errors everywhere else, even using it in a gallery page :

http://www.site.com/page/gallery/2> 404
http://www.site.com/page/gallery/3> 404
etc.

Can you reproduce that ?

2. I want to print 10 random images from the dynamic album called "example"
this way :
<?php printRandomImages (10, 'slide', 'example.alb', '' , '630', '200', true); ?>
But Zp sends me an error saying that this album doesn't exist (but it does...)
Could you confirm that the function syntax above is correct or point me in the right direction ?

Thanks.
