[javascript] How to remove an id attribute from a div using jQuery?

I want to remove the id attribute from this image:

<img width="270" class="thumb" id="thumb" height="270" src="img/1_1.jpg" />

I tried doing this:

$('img#thumb').RemoveAttr('id','none');

But it is not removing the ID!

EDIT:

$('img#thumb').attr('src', response);
$('img#thumb').attr('id', 'nonthumb');

This deosnt load the picture, or in this case the src! But when I remove the id attribute, it works fine

I'm not sure what jQuery api you're looking at, but you should only have to specify id.

$('#thumb').removeAttr('id');
