I need a little help. I do not know where to start. I need to add a page loader to my website. I first submit a form it then uses SimpleXML to call an exterior XML Sheet with expedia... It takes a minute to load, so I would like to add the image loader to this page. But how do I go about doing this? I have looked on Google and could not find any useful info.
I need it to show the loader until the COMPLETE page has loaded.
