In investigating expected thumbnail size requests from the app, I found that talk page header images are not created through the WMFImageWidth enum. We should reference that enum when creating the thumbnail url for the sake of consistency and to avoid unexpected sizes on the backend.
Example of preferred thumbnail url creation:

Thank you for tagging this task with good first task for Wikimedia newcomers!
Newcomers often may not be aware of things that may seem obvious to seasoned contributors, so please take a moment to reflect on how this task might look to somebody who has never contributed to Wikimedia projects.
A good first task is a self-contained, non-controversial task with a clear approach. It should be well-described with pointers to help a completely new contributor, for example it should clearly point to the codebase URL and provide clear steps to help a contributor get set up for success. We've included some guidelines at https://phabricator.wikimedia.org/tag/good_first_task/ !
Thank you for helping us drive new contributions to our projects <3
Hi! This will be my first contribution to the Wikipedia iOS app.
I’ve already set up the project and started reviewing the related code.
Let me know if this task is still available. Thanks!
