Actually, re-reading what you said, I think PhilHow's answer's OK. Here's another page similar to the one above that has the img tags in the html, but the method is basically the same as the first one - the difference being that in the second one, the  images are shrunk by the CSS to 1px dots so that you can't see them and instead, we see the background image of the 'a' tag.

Here's that other page, if you're interested...
