Super simple jQuery background-image random slideshow (using CSS3 for the transition and gets the image paths via HTML5 `data` attribute).

Super simple background image slideshow.css

[data-slides] {
	background-image: url(../../uploads/banner1.jpg); /* Default image. */
	background-repeat: no-repeat;
	background-position: center top;
	background-size: cover;
	transition: background-image 1s linear;
}

/* Use additional CSS to control the `height` of `[data-slides]`, like so: */

.test { height: 220px; }
@media all and (min-width: 48em) {
	.test { height: 320px; }
}

Aweeesome! Nice work @Ema4rl! Thanks for sharing. :)

I copied paste and made some changes but it didn't work.. I'm using CodeIgniter and referenced the image address using base_url()..

$slides.data('slides') return me an string.
So, images.length return "69".
I'm not able to parse items inside the attr data-slides :(

Is possible to add fade effect ?, Thanks for the code.

@inercianet just put transition css to the container

e.g. transition: all 2s ease-in-out;

@fr4nb I know this comment comes too late, but it might help someone else, you probably have a coma at the end of your array data-slides='[1,2,3,]' returns 8 the whole thing as a string, '[1,2,3]' returns 3 as an array.

How would you recommend adding slider dots to toggle through the images?
