[SOLVED] Use an Image in the Post Footer as a divider

I am trying to put a custom divider image into the footer of each post to use as a post separator. I tried to put the following into the ATO > Style Post & Pages > Footer Box

height: 17px;
width: 630px;
background-image: url(/wp-content/themes/atahualpa364/images/posts_seperator.png);
background-repeat: no-repeat;
background-position: left top;

this did nothing.

I also tried to put the following into the ATO>Post/Page Info Items>Footer (all areas but on the pages...)

<div class="entryEND"></div>

and plugged the following into CSS inserts

.entryEND{
height: 17px;
width: 630px;
background-image: url(/wp-content/themes/atahualpa364/images/posts_seperator.png);
background-repeat: no-repeat;
background-position: left top;
}

Again, nothing happened.
