This is something I made a while back for a college project, it's a fairly basic image slider library designed to automate image sliders. You give it the id of an image tag as well as a transition type and a transition speed and it will automate it. 

It's also got some nice functions for manually scrolling, changing the speed and changing the transition that is currently being used. Please don't be too harsh on it because I wrote it when I was just getting to know JavaScript so it's bound to have a few bugs and issues. Although I did use it and thus it has been tested.

The only downside to this is it requires JQuery for the transition effects themself so you're going to have to include that too. Download with documentation
