How do I place a transparent image over specific, centered text?

Question

I'm helping someone with a site that flows sales copy down the center of the browser window. We want to take a transparent oval and place it over a price that will be in the copy. (It would look like someone took a marker and circled the price.)
I had learned that AP Div could solve this problem and, to an extent, it does. I can place the oval right over the price. But it only works when the copy is left justified, not centered. If the copy is centered, I can place the oval, but if the browser window is resized, the oval stays in place while the copy is reflowed to the new browser window size. Thus the oval is no longer over the correct text.
Then I learned that Layout Mode might solve this problem, however that has been removed from CS4.
So now my question is how do I to take a transparent .png file and place it over copy on this site so that if the browser window is resized, the .png file stays with the correct text as the text is "moved" to stay in the center of the brower window?
I want to avoid the workaround of simply creating a .png with the oval and the price and inserting that in the middle of the copy at the appropriate place. There must be a better way to handle this. Not being too familiar with Dreamweaver, maybe there's some sort of Anchor function similar to one in InDesign that solves this issue.
I've attached the simple oval .png file we're trying to use for this.
Thanks in advance for any help.

How about having the circle underneath the text? I know it's a compromise, but it will be much easier to do as you can assign a background image to the div or table cell which holds the text.
For example, make a blank graphic and create a class:
.price
    background-image: url(nocircle.png);
then assign it to the text and give each text div a unique name
<div class="price" id="price1">10.99</div>
then you can turn the background image on and off using Dreamweaver's javascript controls, for example:
onclick="MM_changeProp('price1','','background-image','url(circle.png)','DIV');"
Hope that helps.
