This may be a long shot, but I figured it's worth asking. I need a way to programmatically insert externally linked images in excel, meaning that every time you open the file, the spreadsheet will contact the url at which the image is located. It's easy to do this manually in excel, but I want to do it programmatically, preferably with python. I've tried using the openpyxl and XlsxWriter libraries, but neither have this specific functionality. My only other option is to look for the excel source code so I can see how an externally linked image is represented by excel. I don't suppose Microsoft makes that source code public, do they?
Thanks for any suggestions
