Basic HTML Slider

[Blasteh]

I'm having trouble with this slider. On the 5th, last image, it stays for half the time and instantly swaps back to the first image. How can I make it so it just keeps going around and doesn't do that switch at the end and look fucky. I sped the slider up a bit so you wouldn't have to sit around and watch it for the full 60 seconds.

CodePen:

You must be registered for see links

doing pure css you will have to make 100% go back to the first image, it would be easier for you do use jquery/js to create a slider
