[jQuery] Jquery Iframe problem

[jQuery] Jquery Iframe problem

Hi I want to have an upload script in a page without page refresh. I
coded the script and embedded in an iframe in my page.
Everything works fine. It uploads the file without page refresh. But I
want to show an image which says the page is loading in the iframe.
When the page is loading is there a way to make that happen I cannot
access the document.ready etc in an iframe outside the frame.
