[Javascript] image in div query

[Alan Easton]

Hi Hakan,

Sorry, tried

<img onmouseup="showfull('images/thumb2.jpg')" src="images/thumb1.jpg" />

<script type="text/javascript">

var _oImage = null;
function showfull(sImage) {
	
	if(_oImage) {
		oDiv = document.getElementById('placeholder');
		_oImage = document.createElement('IMG');
		oDiv.appendChild(_oImage);
	}
	_oImage.src = sImage;
}

</script>

and no joy, says _oImage is null or not an object......any ideas......

Err, move the getElementById('placeholder') inside the if(_oImage)-clause.

I'm at work here, ok? ;)
