Select Slider crop images

Hi,
when using the select slider and the full width option, as it has to get adapted to the web browser and screen size that you use, the images are cropped using the top left of the image as the fixed point. Can be possible to set the adaptable option from the center of the image and then adapt it, so you lose less important parts of the image, as normally the most important part is in the center of the image.
You can see an example here: http://www.lukcomunicaciondemos.com/estudiododark/portfolio_page/francisco-suarez/
I hope I have made myself clear. Thanks.
