Atom export missing item images

[BenMcH]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

I found that the atom export did not currently support images in the way that my current RSS feed has them exported. This adds them as I'd expect.

Here is the diff that solved my problem:
