Julien: unless I’m reading it wrong, your test seems to show that appending to an off-DOM node is considerably slower than simply adding to the DOM directly in all browsers tested.

You can make it slightly faster by adding the src attribute when you create the img element ($(’<img>’, { ‘src’ : item });) rather than using a seperate attr() call, but it’s still slower than just appending straight to the DOM – pretty surprising, not what I would have expected.
