hmm. you don't actually need DIVs, just CSS. ok, make your images like this:
Code:
<img class="img1" ...><img class="img2" ...>
Then have this code in the <head> section:
Code:
<style type="text/css">
.img1 {
position: absolute;
left: 150px;
top: 20%;
}

.img2 {
position: absolute;
left: 300px; /* Make this equal to the previous 150+the width of the picture on the left. */
top: 20%;
}
</style>
