Copy an image from one sheet to another sheet?

[MyklClason]

So here is what I'm trying to do:

1. Given an excel file with a single sheet it in (the template sheet)
2. Duplicate that sheet one or more times and changes each sheet (IE: Add rows)
3. The template sheet has an image in it.

This is working generally fine thanks to:

However, I'm having trouble figuring out how to copy the image. I tried the following based roughly on how cells was handled but didn't work out, and after a fair bit of digging around rows and cells I'm a bit stuck as to what to try next. It looks like the row data might have something in but it's a bit to buried for me to debug (ran into an infinite loop of too much nesting trying to inspect it).

worksheet.generic_storage = template.generic_storage.map(&:dup)
