I thought that the blue box was caused because the anchor was smaller in height than the img file. But now you have said that the caused of the blue box i the focus. Well I will try to display:block the image to see if it display inside the anchor. what I am tryiing is that both the anchor and the img match height's.
That why i asked you how can I have the anchor to be the same height as the img tag. If you notice when hover the blue boxed is the anchor.
setting the background to 0 fixed every link that were displaying the same problem since it uses the same styesheet. I used this psudo value once but I don't even remember the functions of it. I know it is use to affect links states colors, when it is clicked, hover or something else.
I'm going go take it everything is solved now lol. It would be best if you have any other questions that you start a new thread lol . Otherwise this thread will go on forever (you have asked half a dozen questions in this thread now , which is fine, but it needs a cut off eventually )
