When exporting a table view to excel, the system is only exporting the data to CSV format - it's plain-text-based so we cannot put any kind of binary data inside. (No hyperlink or image etc.)
I propose that we export to Excel directly, with the ability to include images (like we do for docx) at the moment. This will allow us to create an Excel report with hyperlinks to the actual images/or image thumbnails on the excel reports.
