csv export image field

There is a requirement to export images to Excel file. What you get by csv export will be a URI similar to /core/media/media.nl?id=xxxx&c=yyyy&h=zzzz

I've written an Excel .xla which search for this pattern, prepend https://system.netsuite.com/, then use ActiveSheet.Pictures.Insert(url).Select to attach the image to Excel.
