width and height of the image in the stylesheet empty/not calculated

The problem I mentioned in http://drupal.org/node/168653 was indeed a bug. My co-worker found the solution.

Problem is that the width and height of the image in the stylesheet was empty/not calculated.

Solution is:

change in cck_slideshow.module on line 348:
$image = image_get_info($image[0]['filepath']);
to
$image = image_get_info($images[0]['filepath']);
An extra 's'.

I can't make a patch.
