Answer 1

If i get your question correctly use

document.getElementById("pricefilter").src=ur variable;

One of previuos stackoverflow ques similar to urs showed this

<img src="blank.png" id="image" alt="just nothing">
<script type="text/javascript">
    document.getElementById('image').src = "yourpicture.png";
</script>

Answer 2

Strings can be added together, if variablename contains the path:

document.getElementById("pricefilter").innerHTML ='<img src="' + variablename +
  '/spinner.gif" title="Loading..." alt="Loading...">';
