Image alignment help

[adammc]

Hi guys,

I was hoping someone could help?
I have the following css which controols the style for a larger image on hover function. (thumb - then large pic on hover)

I am having trouble positioning (vertically) the image, what can I usew to control it?

/* Popup Image Viewer */
.thumbnail{
position: relative;
z-index: 0;
}
.thumbnail:hover{
background-color: transparent;
z-index: 50;
}
.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: #669933;
padding: 1px;
left: -1000px;
border: 1px ridged;
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 on hover*/
visibility: visible;
top: 0;
left: 135px; /*position where enlarged image should offset horizontally */
}
