Dynamic Display Module does not display, how should the theme directory structure be?

I am having problems getting a dynamic display block to display. Nothing appears in the place where it should and I think it comes from the content type "News item."

I used the Advanced slideshow tutorial. The error message that displays is:

node_data_field_image_field_image_data (String, 68 characters ) a:3:{s:11:"description";s:0:"";s:3:"alt";s:0:""...

I removed the image description field from the content type, but the message keeps popping up like it did not get removed completely. I tried removing all content and flushing all caches, then re-creating content, but they apparently still have the field.

Here is the content of my template.php file (sites/all/themes/garland):
