During the discussions surrounding controversial content, there has been a(n uncontroversial) suggestion that MediaWiki / Wikimedia wikis should have a functionality where no images (in the content area) are loaded when the rest of the page loads and are instead replaced with placeholder images. When the placeholder is clicked, the image being click would be loaded asynchronously.
This functionality has a variety of uses:
- "safer" browsing in environments where you may be confronted with surprising images (at work, during presentations, etc.)
- much, much faster load times on mobile devices or even on desktop devices
Toggling the image switch could be done via user preference or via a link in the toolbox.
