On your example page you have the carousel type. It consists of a total of 11 images - with 3 images on screen and a horizontal scroll. What I would like to have is a total of 12 images - but with 4 images on screen - and still have the 'one-by-one effect' from the example.
I've tried to accomplish this by resizing images and adjusting the size in the Meta Slider options. But the only thing I've achieved is stretched out, ugly-looking images. And if by resizing images I have 4 images on screen then 3 of them disappear at once while scrolling horizontally. I hope you understand what I mean. :-)
Some help would be much appreciated. I would post a link to my website, but I just started with WordPress, am still in the tinkering phase and I'm working localy with Wampserver and Twenty Twelve theme.
