图像悬停在javascript上

Question

i am trying to display additional info over an image by using two overlay images. on mouse hover overlay1 will be displayed at the top left corner of the main-image and overlay2 will be at bottom right..

when i try this to do on a single image it works fine.. but as i get on to do it on gallery of images the overlay images displays at the top-left and bottom-right section of the screen..

i want the images to be overlay-ed on the respective main-images..

here is the html-

<div id="WhizIt">
<div id="btpanelexsmall">
<h3>Heading1</h3>

<ul >
<li><a href=""><img src="image/" class="wit"/><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>
</ul><br>

<ul>
<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>

<li><a href=""><img src="images/arrow1.jpg" class="wit" /><img class="overlay"  
src="image/top-left.jpg"/>
<img class="overly" src="image/bottom-right.jpg"/></a></li>
</ul>
</div>
</div>

the script is-

<script src="js/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
            $('ul li').mouseenter(function() {
                $(this).find(".overlay").show();
                $(this).find(".overly").show();
            });
            $('ul li').mouseleave(function() {
                $(this).find(".overlay").hide();
                $(this).find(".overly").hide();
            });
        });
</script>

and the css-

.WhizIt li{position:relative;
float:left;
padding-left:5px;
list-style:none;}


.overlay 
{
position:absolute;
height:50px;
width:150px;
top:0;
left:0;
display:none;}



.overly 
{
 position:absolute;
 height:50px;
 width:150px;
 bottom:0;
 right:0; 
display:none;}

 #btpanelexsmall{height:390px;
 margin:0px;
 padding:0px;
-moz-border-radius: 10px;
-webkit-border-radius: 10px;
border-radius: 10px; /* future proofing */
border:2px solid yellow;
background: #f0f0f0;}

i have many galleries on my page!! thanks in advance

I think your 1st problem is solved. Now to give 'rotate' effect to the overlaying images use css3 animation. We can do it with jquery also but I think using css3 will be good.

For this effect, use this script:-

 $(document).ready(function() {
                $('ul li').mouseenter(function() {
                    $(this).find(".overlay").show().addClass('rotate');
                    $(this).find(".overly").show().addClass('rotate');
                });
                $('ul li').mouseleave(function() {
                    $(this).find(".overlay").hide().removeClass('rotate');
                    $(this).find(".overly").hide().removeClass('rotate');
                });
            });

Add this css:-

.rotate {
    -webkit-animation: rotateImg 1s linear;
    -moz-animation: rotateImg 1s linear;
    -ms-animation: rotateImg 1s linear;
    -o-animation: rotateImg 1s linear;
    animation: rotateImg 1s linear;
}

@keyframes "rotateImg" {
    50% {
    -webkit-transform: rotate(180deg);
    -moz-transform: rotate(180deg);
    -o-transform: rotate(180deg);
    -ms-transform: rotate(180deg);
    transform: rotate(180deg);
}
100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    transform: rotate(360deg);
}

}

@-moz-keyframes "rotateImg" {
    50% {
    -moz-transform: rotate(180deg);
    transform: rotate(180deg);
}
100% {
    -moz-transform: rotate(360deg);
    transform: rotate(360deg);
}

}

@-webkit-keyframes "rotateImg" {
    50% {
    -webkit-transform: rotate(180deg);
    transform: rotate(180deg);
}
100% {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
}

}

@-ms-keyframes "rotateImg" {
    50% {
    -ms-transform: rotate(180deg);
    transform: rotate(180deg);
}
100% {
    -ms-transform: rotate(360deg);
    transform: rotate(360deg);
}

}

@-o-keyframes "rotateImg" {
    50% {
    -o-transform: rotate(180deg);
    transform: rotate(180deg);
}
100% {
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
}

}
