What steps should I take to create a script that can manipulate elements of a webpage when a specific DIV is visible on the screen?

I am working on customizing the carousel on my website roseannebarr.tumblr.com. My plan is to add a dedicated "About" button on the left side of the carousel. When this button is clicked, I want a "left" arrow to appear in its place. I am new to Javascript and unsure if I should use if else statements for this task. Any advice or assistance would be greatly appreciated.

Is it possible to dynamically add a div using a JavaScript function?

Essentially, you place the div on the carousel with a span containing clickable text "About". When clicked, it triggers a JavaScript function.

The JavaScript function then inserts a new image within the span. The image can also be turned into a hyperlink if required.

<script type="text/javascript>
function ShowArrow(spn){
   document.getElementById(spn).innerHtml('<img src="path_to_your_image" />');
}
</script>

<div style="float:left">
  <span id="spnAbout" onclick="ShowArrow(this.id);return false;" style="background-color:#ccc;padding:5px;cursor:pointer">About</span>
</div>

If utilizing jQuery, the function would appear as follows:

function ShowArrow(spn){
   $('#'+spn).html('<img src="path_to_your_image" />');
}
