Text /Pic Replace

[neo_philiac]

Its just a simple thing but I forgot how to do it. I just want to replace the text with Picture when mouse-over. Its an overlap thing. Can anyone give me the code?

<span
onmouseover="
while(this.hasChildNodes)
this.removeChild(this.firstChild);
this.appendChild(
document.createElement('img')
).src = '/path/to/image.png';
this.onmouseover = null;
"
>
Some text
</span>
