"Obviously"

There are plenty of use cases where the filename is relevant (and many, many people intentionally use the image name for sorting / cataloging).

There are many, many more cases where the user doesn’t expect the name to become public when he sends a photo. If I send you a photo of a friend that doesn’t mean I want you to know his name (which is the name I gave the file when I saved it)

		So in webmail, when you upload an image / file to attach it to an email, you expect it to be renamed? I don't.
