Looping Slideshow

I want to make a slideshow to scroll across the width of my site. I only have 6 photos, so I want it to somehow have a seamless loop to where there isn’t an obvious start and stop, just Image 6 is followed by Image 1. I imagine this wouldn’t be difficult, but I haven’t had any luck in figuring it out. I googled different things and found other tutorials, but they didn’t lay it out basic enough and also had bells and whistles like enlarging the photo when you rollover, or being able to change the speed.

None of that for me. Just need a simple, slow-scrolling slideshow of 6 photos to loop over and over…and over. If anyone has any hints, it would be hugely appreciated!
