این رو هم خودم پیدا کردم :
<style type="text/css">
/*Credits: Dynamic Drive CSS Library */
/*URL: http://www.dynamicdrive.com/style/ */
.gallerycontainer{
position: relative;
/*Add a height attribute and set to largest image's height to prevent overlaying*/
}
.thumbnail img{
border: 1px solid white;
margin: 0 5px 5px 0;
}
.thumbnail:hover
{
background-color: transparent;
}
.thumbnail:hover img{
border: 1px solid blue;
}
.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: lightyellow;
padding: 5px;
left: -1000px;
border: 1px dashed gray;
visibility: hidden;
color: black;
text-decoration: none;
}
.thumbnail span img{ /*CSS for enlarged image*/
border-width: 0;
padding: 2px;
}
.thumbnail:hover span{ /*CSS for enlarged image*/
visibility: visible;
top: 0;
left: 230px; /*position where enlarged image should offset horizontally */
z-index: 50;
}
</style>
<div class="gallerycontainer">
