thanks for your works Matthew....
Now i get a problem with the dimension of the images added to the slider.
All the images look like Zoomed-in and so results cropped (i try with sizes bigger and smaller than the sliderbox but nothing change... all resaults not the same original size).
In the setting i get 1280x350 responsive and the images are:
In the slider all the images miss something around.
Please take a look to the page... and when possible let me know how to solve the problem.
Where can i set that the images must fit the slider-box and have to be diplayed as they are ???
