So I see the image sourcing through URL has been updated to include only a list of approved image hosting websites - Imgur, ImgBB, Postimage.
However, Wikimedia Commons is not an approved source; this means that worldbuilding or factbook pages which use Commons as a source of images now have to be rewritten. Here's a good example - all the unit symbols are sourced from Commons, which, above all, allows resizing of png images just by adding a string at the end of the URL, which is super convenient. Now to edit this page, I need to download all these PNGs, resize each of them manually, upload to Imgur/ImgBB/whatever, and re-link.
I'd strongly suggest Wikimedia Commons is added as an approved source of images, not just because of cases like this one, but purely out of convenience to anyone else who might want to use it.
Images in Commons are moderated, scalable and come in a variety of formats, they're perfect for illustrating anything from factbooks to posts to dispatches, and on top of that there's no breach of copyright (which probably wouldn't be the case with most other image hosting websites).
