I have Simpleviewer theme installed on my photography website, with nextGEN gallery plugin and nextGEN Smooth gallery viewer. it works very well and looks like this: http://louisvorster.co.za/portraits-1/
but after 2 years I'm up for some changes, and I like this type of horizontal scrolling gallery that comes standard with the Epositio theme: http://expositio.wpshower.com/?p=6
Does anybody know if there's a gallery viewer plugin that can do this?
