/*To determine the size of the IFrame's contents, you must access the height and width properties of the underlying IFrame document. Because you only have scripting access to pages that are hosted in the same domain, you can only access the properties to the pages that are hosted within the same domain (for example, Cross Frame Scripting). Therefore, the source document of the IFrame must be from the same domain as the page that contains the IFrame. From: http://support.microsoft.com/kb/278469*/
