Fade effect?
Fade effect?
Hi,
I'm using jqGalScroll v2.1 for a slideshow on my pages, it works great, but just lacks one thing - fade effect.
Is there any way I could fade the slides instead of horz/vert/diag slide effect?
Here's the script code:

* @extendThanks Koesmanto Bong http://www.koesbong.com/
* Koes put a fire under my butt to improve this plugin
* and when I took too long he took what I had and added
* the horizontal scroll and in turn I ripped it from his
* hands and made it better :)

* @example $('#gallery').jqGalScroll({speed:1000});
* @param String speed
* fast, slow, 1000, ext..
*
* @example $('#gallery').jqGalScroll({speed:1000});
*
* @param String height
* the default height of your wrapper
*
* @example $('#gallery').jqGalScroll({height:490});
*
* @param String titleOpacity
* the opacity of your title bar (if present)

* @example $('#gallery').jqGalScroll({titleOpacity:.70});
*
* @param String direction
* vertical horizontal diagonal
