IE7 CSS image link color border problem

I just noticed this problem today checking my site
with internet explorer 7. It deals with an image
border's color changing on a mouseover effect. Here's
the CSS which should do it:

a img {
color: #fc86c3;
text-decoration: none;
}
a:link img {
color: #fc86c3;
text-decoration: none;
}
a:visited img {
color: #fc86c3;
text-decoration: none;
}
a:hover img {
color: #FFFFFF;
text-decoration: none;
}
a:active img {
color: #fc86c3;
text-decoration: none;
}

and here's the page i'm trying to solve the problem
with http://www.remati.net/test.php

if you click the image or the link it should show you
the full style sheet.

Everything works fine when i view the page in firefox
but when i try it in internet explorer 7 it just keeps
the border color the default blue color. What is the
problem?
