HTML positioning of divs above image

Question

I have a large image, and a bunch of divs that I'm using as fake buttons on top of said image. Currently, I'm using absolute positioning to place the divs where I want them to be, but I've got a lot of divs, and finding the x/y coords by trial and error is time I don't want to take. Is there an easier way to position them, or am I stuck?

I'm using jQuery and Javascript in this project, so these can be used for solutions.

CSS:

#test0 {
position:absolute;
    left:381px;
    bottom:100px;
}

HTML:

<div id="image">
    <div id="test0" class="button" onclick="$('#modal').dialog('open');" style="postion:absolute">
        Click me to test Modal!
    </div>
    <div id="test1" class="button" onclick="$('#modal').dialog('open');" style="postion:absolute">
        Click me to test the same Modal!
    </div>
    <img src="testImage.jpg" alt="testtest" />
</div>

HTML:

<div id="image">
<div id="container-of-fake-divs">

<div class="fake-div">FAKE DIV</div>
<div class="fake-div">FAKE DIV</div>

</div>

<img src="image.jpg" />

.fake-div { display:block; }
