Continuo a pensare che non ne valga la pena... ma purtroppo mi piacciono le sfide

ecco l'esempio:
codice:

<HEAD>
<script>
var spFlag=false;
var osx=0;
var nsx=0;

function spMove(o) {
	if ( spFlag ) {
		nsx = event.screenX;
		ll = parseInt(document.getElementById(o).style.width) + nsx-osx
		document.getElementById(o).style.width=""+ll+"px"; 
		osx = nsx;
	}
}                                                   
                                                                
function spDown(o) {
	document.body.style.cursor='move';
	spFlag = true;
	osx = event.screenX;
	
}

function spUp(o) {
	document.body.style.cursor='auto';
	spFlag = false;
}

function selectstart(){
	if ( event.srcElement.tagName != "INPUT" && event.srcElement.tagName != "TEXTAREA") { return false; }
	else { return true; }
}                                                      

document.ondragstart   = new Function("return false;");

</script>
</HEAD>

<BODY>
<table border=1 cellpadding=0 cellspacing=0>
	<tr>
		<td nowrap>
			<div id="t1" style="width: 20px;display: inline;"></div>
			[img]nero.gif[/img]

</BODY>
