No images in Slideshow

now I see
you have a big problem in your website because no css and no js is loaded except the ones from the template
Please try with the template protostar to see if it works and disable jquery easy which shall not be used with joomla 3

Ok, there it works. What js or css do I have to include?

check that your template has the <jdoc:include type="head" /> in the index.php code

Thank You, now it works, I had an error in my scripting so that jquery could not be loaded.
