Random image php question?

I’m using the random image plugin. But now I want to show random images from the category where one entry is in (I’m using this in single.php).

<?php randomimage(show_post_title,
                  number_of_images,
                  image_attributes,
                  show_alt_caption,
                  image_src_regex,
                  post_type,
                  inter_post_html,
                  category_filter,
                  sort_images_randomly,
                  image_class_match,
                  image_template_html); ?>

Now I’m using this:

<?php randomimage(true, 4, "width='88'", false, "(.gif)", posts, "", "<?php the_category_ID(); ?>", true, "", ""); ?>

But that won’t do the trick. So, how can I do this?
