"img_image_proxy" attach instead of image on sharing image

Hello!

More recently, when attempting to share some images to Element (chat client), I see the following:

I suspect this is file specific or mimetype, as it's consistent on a given image but doesn't seem to affect most images.

A source of an example image is https://lemmy.dbzer0.com/post/42991557 ...

In these cases, saving the same image then attaching it separately inside the chat client works normally.

Please let me know if I can help diagnose etc.
