Let's say you're doing a discussion forum, and you want to allow user's to upload their own avatars. Other user's viewing my posts, will normally want my avatar to show.
Why would an app _not_ cache avatars?
Similarly, if a meme image is popular and get's reposted in multiple separate discussion threads, the same question: why would the app re-download that image every time it has to display that image, or even after shutting down and restarting the app or device? Surely failing to cache such things is a needless deficiency which would be called a bug by most user's?
(Modulo cache aging, purging etc.)
