A way for a reader to see thumbnails/resized versions in other sizes
The reader should be able to view galleries and image pages with
the images resized to other sizes than a single default one: it is
not possible for the browser to scale thumbnails up infinitely
without losing their quality.
- Flickr has at least "small" and "medium" gallery views, and
several sizes for viewing and downloading of individual images.
- MediaWiki allows registered users to choose from several
thumbnail sizes for viewing of pages, and to generate a thumbnail
of any size.
