putting an img tag inside of an a href tag causes a border around image in IE

Simple fix, in your stylesheet create a style similar to this:

a img{
border:0;
}

In your case, you could update your style to include some of the inline styles you have in your HTML. For example, your stylesheet would be updated to:

a{
cursor:pointer;
text-decoration:none
}

a img{
margin-top:600px;
}
