I was just about being done with a class that fetches emails from my Gmail account, until this showed up:

HTML Code:
<img src="cid:ii_13a30f914dff78c5" alt="Billede indsat i tekst 1">
I know the image is called "image.png" because it's the only one, but how do I decode the path/filename from "cid:ii_13a30f914dff78c5" ?

I'm full of hope
