Links by default have an underline. An image link by default doesn't have the underline link, but rather a border around the image.
Also by default the "link" selector or unvisited link is blue, while a visited / selected link is purple.
To get rid of these, add a CSS border rule to the image links and you will see them disappear
Code:
a:link img, a:visited img, a:hover img, a:active {border:none}
and now any image link on the page will now disappear.
You did this properly, but whenever you are declaring pseudo selectors, you should do them in the order of
:link
:visited
:hover
:active
If you find it difficult to remember that order think of it this way
