In the classic yahoo mail inbox, there was a way to easily see all of the pictures that were attached to emails. This was very helpful. Not all attachments are pictures, so searching for emails with attachments isn't the same. And searching for emails with pictures is different because a lot of spam (or bulk non-spam) has pictures in the body, so it's cumbersome to sort that way. I just want that 'photos' button under 'views' back!
