Images not showing and "Invalid argument supplied for foreach()" error

I have been installed advanced ddblock by tutorial, by importing views and cck. I read documentation and tutorials carefully.

Theme are installed in sites/all/themes/agnian

Uncommenting drupal_set_message functions returns, "ddblock-News item slideshow".

This is my template.php
