<img src="/images/new.gif">always put the WIDTH and HEIGHT in even if it is a small image so it looks something like:
<img src="/images/new.gif" width=28 height=11>That will make your pages load much faster and make all us with modems instead of a T-1 much happier :)
Another thing you can add is the ALT which gives text based browsers an idea of what the picture is. It also lets people know what the picture will be of before it loads. It would look something like this:
<img src="/images/new.gif" width=28 height=11 alt="new">
