And what is not working if you export this straight table? Do you get the broken-image-icons?
QlikView will probably embed the same image URLs in the export. If they are relative to the current site, this won't work in Excel as there is no site anymore. And furthermore, as soon as the Excel file moves out of scope of your QlikView server, the references will break again.
Can you provide some more details about how your straight table refers to those images?
