java script grapics hyperlinks

I have been away from SEO for a couple of years so I need to check to see if some things have changed.

Is it still believed that major search engines cannot follow java script graphic hyperlinks such as below?

<script language="javascript">

function scramSShow() {

window.location = "http://www.xxx.com/Slide-Show.htm"
}

</script>


<img src= "SShow.gif" onclick="scramSShow()" width="96" height="44" /><br>

Thanks Larry
