I am wondering if it is possible to edit the photo slider content widgets in WD10. I am trying to get an effect something like the header on this site: http://www.odfjelldrilling.com/

So I would ideally like to change the graphic attributes so that, say, instead of numbers there are arrows at each end. Alternatively, is it possible to build such a content slideshow from scratch and is there a tutorial available for this? Thanks.
