html - Access Multiple Elements of same ID in jQuery

If i have elements such as this

<img src='0.jpg' id='images' />
<img src='...' id='myEle' />
<img src='...' id='myEle' />

in jQuery can i do something like this

$(document).ready(function() {
    $('#myEle').mouseup(function () {

        $('#images').attr("src", myEle.getNumber() + ".jpg"); 
    }
}

Obviously each element is sorted in the correct number format that corresponds to the myEle array number

Do not create markup that contains elements with duplicate IDs. This will break things, and you will be mauled by a velociraptor faster than you can say "goto".

Use classes instead:

<img src='0.jpg' id='images' />
<img src='...' class='myEle' />
<img src='...' class='myEle' />

then...

$(document).ready(function() {
    $('.myEle').live('mouseup', function () {

        $('#images').attr("src", myEle.getNumber() + ".jpg"); 
    });
});

Re: OP comment

"How do i know which image is pressed?"

Use the this keyword:

$(document).ready(function() {
    $('.myEle').live('mouseup', function () {

        $('#images').attr("src", $(this).attr('src')); 
    });
});

...I think that's what you're looking for.
