.thumbnail:hover
{
position:relative;
top:-25px;
left:-35px;
width:500px;
height:auto;
display:block;
z-index:999;
}
and
<td><img src='.$row['spy'].' class="thumbnail" style="width:64px; height:64px;"></td>
But it won't work btw I'm using Enjin I'm trying to make an image bigger on hovering over it
