By click on right side of img show next img, on left show prev img, i make the event on click img and it work, but standart processing still continue show next img, than I add options to your plugin, if it can be done otherwise, show me plz.

Add ability to disable the default processing on click, add option onClickNext: true, if false it does not show next image.
