I would like to know your suggestions about the best slideshow module to images uploaded from CCK image field. When I mean best, I want to say quality/quantity of features supported according your experience, but if you know another criteria (like support), please feel free to give your suggestion according your criteria.
Well, there is of course this page in the drupal docs: http://drupal.org/node/418616
Unless you have a very specific use case which can be accommodated by a specialized module you really should go with the views slideshow module (http://drupal.org/project/views_slideshow). Very well maintained, fairly well documented (but a lot of tutorials flying around) and a lot of modules integrating with it. With this module you can do almost everything slideshow-wise but it might be a bit complicated (but again: lots of tutorials available).
You can of course check out some of the other modules if they offer something more matching to your specific needs.
