So I have upzipped a Powerpoint 16 presentation and I am looking at the XML from a slide from the ppt/slides/ directory. I am searching for a reference to the image that is place on this slide, I THINK it is one of the <a:ext uri=
references, but if it is I have no clue how to decode that URI into something readable. I just need the name of the image placed in the file. I am currently working on these files as text files mostly from the command line or using BBEdit.

So am I close? Is it one of those URI's? If so, how do I decode it? If it is not one of those URI's then were would I find a reference to the slide on the file. I have done the obvious and searched the entire pptx zip file and have not found anything with .jpg in the text that references a file. I realize this is a lot to ask in a single question, and for that I am sorry. I am just sort of lost at the moment.
