JS photo slideshow

[abilene]

Hi, I am somewhat new to javascript and website design, (as in I mostly try to follow tutorials to figure how stuff works) and was wondering how I would make a rotating photo slideshow (in js).

Such as in the following sites:
http://www.1stwebdesigner.com/wp-con...inal_small.jpg

and

http://www.1stwebdesigner.com/wp-con...inal_small.jpg (but instead of clicking on the photos to rotate, an arrow to rotate, such as in the first image/example)

Thanks so much in advance
