[jQuery] attr('title') giving odd renaults

[Nathan]

I'm using attr('title') to find the title of the first anchor in a
list and then make that title the value of an alt tag for an image.

        $('#imageswap a:first').attr('href', function(){
                var altName = $(this).attr('title');
                $('#productimage').append('<img src='+ this +' alt='+ altName +'
class="product" />');
                $('img.product').fadeIn(1000);
        });

The problem is if the anchor title has spaces (title="firstWord
secondWord thirdWord") it gives me:

        <img class="product" thirdword="" secondword="" alt="firstWord"
src="imageName.jpg"/>

Any ideas on why it's doing this? I can't figure it out.
