I understand that we can not export image / shapes/ vba, etc. when we save an Excel spreadsheet as XML. I am creating a spreadsheet via a web process (it doesn't matter which). I gather the data and apply an XSLT template to the data and deliver it in the response buffer (after setting the content type too). This all works great - i have found a ton of examples on how to do this ASP, .Net - etc.
But how, there has to be a way, do I insert an image (logo) at the top of the spreadsheet report during this transformation?
