Welcome to the Internet!
This is Domesticated, a free, fully standards-compliant CSS template designed by Free CSS Templates. The slideshow uses photos from PDPhoto.org and is powered by Slidertron (a jQuery plugin by NodeThirtyThree). This free template is released under a Creative Commons Attributions license, so you’re pretty much free to do whatever you want with it (even use it commercially) provided you keep the links in the footer intact. Aside from that, have fun with it :)
