WTF src für img Element

[Beat]

Vielleicht steckt das Problem in deinen '...'.

Hier der Code, der nach des JS Ausführung im Browser steht

  
<div class="plugin gallery">  
<noscript>  
<ol>  
  <li><img src="userdata/img/humor1.png" alt="MISSING"></li>  
  <li><a href="__?plugin_gallery=1"><img class="preview" src="userdata/img/humor2.png" alt="MISSING"></a></li>  
</ol>  
</noscript>  
<div id="plugin_gallery">  
<div><span>1</span><span>2</span><span>3</span><span>4</span><span>5</span></div>  
<img style="margin: 0pt auto; display: block;" alt="MISSINGuserdata/img/humor5.png"></div>  
  
<!-- HIER ^^ sieht man dass src nicht eingetragen ist -->  
  
<script type="text/javascript">  
var _gal = new Object;  
_gal.img = new Array;  
_gal.img[0] = ["userdata/img/humor1.png","MISSINGuserdata/img/humor1.png",];  
_gal.img[1] = ["userdata/img/humor2.png","MISSINGuserdata/img/humor2.png",];  
_gal.img[2] = ["userdata/img/humor3.png","MISSINGuserdata/img/humor3.png",];  
_gal.img[3] = ["userdata/img/humor4.png","MISSINGuserdata/img/humor4.png",];  
_gal.img[4] = ["userdata/img/humor5.png","MISSINGuserdata/img/humor5.png",];  
  
_gal.prev = document.createElement("div");  
_gal.show = document.createElement("img");  
_gal.show.src = _gal.img[0][0];  
_gal.show.alt = _gal.img[0][1];  
alert(_gal.img[0][0]); // prints fine <-----------  
alert(_gal.show.src);  // empty <--------------  
alert(_gal.show.alt); // prints Fine <-----------  
//_gal.show.alt = "DEFAULT";  
_gal.show.style.display="block";  
_gal.show.style.margin="0 auto";  
for( var i=0; i < _gal.img.length; i++ ){	  
	var e = document.createElement("span");  
	e.innerHTML = (i+1);  
	e.onclick = function(){  
		alert(this.firstChild.data);  
		var c = this.firstChild.data - 1 ;  
		_gal.show.src = _gal.img[c][0];  
		_gal.show.alt = _gal.img[c][1];  
	};  
	_gal.prev.appendChild(e);  
}  
_gal.cont = document.getElementById("plugin_gallery");  
_gal.cont.appendChild(_gal.prev);  
_gal.cont.appendChild(_gal.show);  
</script>  
</div>
