Removing link from slideshow images
Without knowing how your view looks like (or what slideshow module you use, if any) it is hard to give a definite answer - but check the image field in your view. If you edit the field there should be an dropdown titled 'link this image with' and right now it is probably set to 'content'. Set it to 'nothing' to remove the link.

Note: I am not sure about the exact labels as I work with a german drupal instance right now, but they should come close. The dropdown is right above the Design Settings fieldset.
