CSS3 Crossfading various images - html

Question

I have 4 images that I would like to crossfade using CSS inside a container:
<div id="frame">
<img class="img1" src="img1.jpg">
<img class="img2" src="img2.jpg">
<img class="img3" src="img3.jpg">
<img class="img4" src="img4.jpg">
</div>
I know that crossfading images consists of a CSS animation, but I haven't been able to find the CSS to make it work. Any help would be appreciated, thanks!

Here is a Fiddle
It's easier with 2 pictures, but as your wrote 4 you need to do this as CSS:
#-webkit-keyframes cf4FadeInOut {
0% {
opacity:1;
}
17% {
opacity:1;
}
25% {
opacity:0;
}
92% {
opacity:0;
}
100% {
opacity:1;
}
}
#-moz-keyframes cf4FadeInOut {
0% {
opacity:1;
}
17% {
opacity:1;
}
25% {
opacity:0;
}
92% {
opacity:0;
}
100% {
opacity:1;
}
}
#-o-keyframes cf4FadeInOut {
0% {
opacity:1;
}
17% {
opacity:1;
}
25% {
opacity:0;
}
92% {
opacity:0;
}
100% {
opacity:1;
}
}
#keyframes cf4FadeInOut {
0% {
opacity:1;
}
17% {
opacity:1;
}
25% {
opacity:0;
}
92% {
opacity:0;
}
100% {
opacity:1;
}
}
#Crossfading {
position:relative;
height:281px;
width:450px;
margin:0 auto;
}
#Crossfading img {
position:absolute;
left:0;
}
#Crossfading img {
-webkit-animation-name: cf4FadeInOut;
-webkit-animation-timing-function: ease-in-out;
-webkit-animation-iteration-count: infinite;
-webkit-animation-duration: 8s;
-moz-animation-name: cf4FadeInOut;
-moz-animation-timing-function: ease-in-out;
-moz-animation-iteration-count: infinite;
-moz-animation-duration: 8s;
-o-animation-name: cf4FadeInOut;
-o-animation-timing-function: ease-in-out;
-o-animation-iteration-count: infinite;
-o-animation-duration: 8s;
animation-name: cf4FadeInOut;
animation-timing-function: ease-in-out;
animation-iteration-count: infinite;
animation-duration: 8s;
}
#Crossfading img:nth-of-type(1) {
-webkit-animation-delay: 6s;
-moz-animation-delay: 6s;
-o-animation-delay: 6s;
animation-delay: 6s;
}
#Crossfading img:nth-of-type(2) {
-webkit-animation-delay: 4s;
-moz-animation-delay: 4s;
-o-animation-delay: 4s;
animation-delay: 4s;
}
#Crossfading img:nth-of-type(3) {
-webkit-animation-delay: 2s;
-moz-animation-delay: 2s;
-o-animation-delay: 2s;
animation-delay: 2s;
}
#Crossfading img:nth-of-type(4) {
-webkit-animation-delay: 0;
-moz-animation-delay: 0;
-o-animation-delay: 0;
animation-delay: 0;
}
