[Solved] How to line up floated img to left side of div?

So I am trying to lineup an img to the very left of my div yet it is keeping some spacing even after setting padding/margin to 0. Anyone have a workaround or explanation? Thanks, Ben

.ad
{
padding: 0;
margin: 0;
display: block;
border: solid 1px black;
margin-left: 0px;
width: 405px;
margin-left: 27px;
overflow: hidden;
}

.ad img
{
margin: 0px 10px 0px 0px; padding: 0px 0px 0px 0px;
float:left;
clear: both;
}
