I am trying to put an image on a CommandBar Button and I am currently using
the .PasteFace method to do so. I know there is a .Picture method to add an
icon to a button. However, I have not been able to figure out how to get the
..Picture method to work.

I want to load a picture from a spreadsheet within my add-in. However, all
the examples I have found on the internet show how to use the .Picture method
by giving a file path to an image.

Any ideas on how to reference a picture/icon in a spreadsheet?
