How to add image between blog posts

Question

I'm trying to figure out how to add an image between blog posts (i.e., a graphic basic divider line, not a border) on my website: www.sacspartans.org

I know how to create and div, add the image, etc. But I don't know what file to make the modification to. Does anybody know?

I'm using Toolbox, the bare bones starter theme.

Any help would be much appreciated.

EDIT: I opened up the index file... but I'm not sure where to add my div.

Answer 1

Add the div right above <?php endwhile; ?>

Answer 2

Make it so that the three divs are like this:

<div class="div">
//blogpost 1
</div>

<div class="div">
//pic
</div>

<div class="div">
//blogpost 2
</div>

CSS

.div {
float: left;
display: inline;
//rest of css
}
