I am attempting (and failing) to add an image to a map layout using ArcObjects via Python comtypes. I do need to run this outside of ArcMap (i.e. not in the ArcMap Python window).
The basic idea is: open mxd, place jpg in layout, save/close mxd.
Python solution preferred, but I would also accept a similar workflow in VB.NET.
Using ArcGIS 10.2.2, Python 2.7.5
Script:
