What you need is a tooltip plugin. There are plenty of them. Check out this list: https://cssauthor.com/jquery-css3-hover-effects/

<img class="enlarge-onhover" src="img.jpg">

...

And on the css:

.enlarge-onhover {
     width: 30px;
     height: 30px;
}

.enlarge-onhover:hover {
     width: 70px;
     height: 70px;
}

Take a look at http://fancybox.net/blog

Fancybox looks nice, uses JQuery and is highly configurable with various show/hide effects. Tutorial number 3 on this page shows you how to use it OnHover rather than OnClick

The home page http://fancybox.net/home shows some examples of the visual effect

<script>
function bigImg(x) {
   x.style.height = "64px";
   x.style.width = "64px";
}

function normalImg(x) {
   x.style.height = "32px";
   x.style.width = "32px";
}
</script>

<img onmouseover="bigImg(this)" onmouseout="normalImg(this)" border="0" src="smiley.gif" alt="Smiley" width="32" height="32">

The function bigImg() is triggered when the user mouse over the image. This function enlarges the image.

The function normalImg() is triggered when the mouse pointer is moved out of the image. That function sets the height and width of the image back to normal.
