How to set the image src using jQuery

I am trying to change the image src attribute using jQuery

jQuery("#imageID").attr('src','http://localhost:8080/images/1/myImage.png' );

using the above code i can change the src attribute, but when i try this:-

jQuery("#imageID").attr('src',jQuery("#imageBlock").css('background-image') );

i am unable to change the src.

provided

alert ( jQuery("#imageBlock").css('background-image') );

returns:

url(http://localhost:8080/images/1/myImage.png)

Edit #1 Just when i was about to accept the solution. I must say, almost all solution worked in FF. I tried:

• slice(4,-1);
• split("(")[1] > then replace ( ")" , "" );

I guess others will also work. But none of the solutions is working in IE. Reason being: while FF returns:

url(http://localhost:8080/images/1/myImage.png)

IE Returns:

url("http://localhost:8080/images/1/myImage.png")

^^ mind the quotes here

Now, what could be the generic way to set the src attr. Do i need to test the browser if it is IE or not?

This is the working code.

var src = "";
    if ( jQuery.browser.msie ) {
        src = jQuery("#imageBlock").css('background-image').slice(5,-2);        
    }else{
        src = jQuery("#imageBlock").css('background-image').slice(4,-1);
    }   
    jQuery("#imageID").attr('src', src );

I really don't like it :x. If there is another solution than this, then please let me know or else i will accept the slice solution straight away.
