I don’t know what “image proxying” is. Can someone give me the q&d?
Is it the "?format= " at the end of a url that usually turns a quick download of a .jpg or .gif into a .webp or .webm download?
I especially hate it when the source is already the same as whatever the target is, but it still breaks the image. Removing the format parameter suddenly makes the image work again, it’s so dumb.
