category problem

[okapi]

on my "archives" page (test run) i'm trying to get the latest images from several categories with a snippets code like the following:

<?php
include("http://www.a-visual-notebook.at/photolog/snippets.php?get=latest_photos&amount=50&border=1& bordercolor=666666&hspace=3&vspace=3&viewas=image& thumbsize=microthumb&includecategory=4&excludecate gory=1|2|3|5|6|7|8|9|10|11|12|13|14|15");
?>

but whatever i try, include/excludecategory has absolutely no effect, all what i get is just the latest 50 images.

in photo editor i have defined categories for every photo. so, what am i doing wrong?[/code]

i have learned the following:

1) include/exclude does only work with random_photos.
2) it seems to not work if photos are referred to more than one category.
