Our image option markup should have the means of applying site-wiki image options, customized by the administrators of the wiki.
For example:
```
[[File:Foo.jpg|style=thumb]] (replaces the existing 'thumb' option)
[[File:Foo.jpg|style=largethumb]] (used by nlwiki to apply a second "larger" thumbnail size)
[[File:Foo.jpg|style=fullwidth]] (appropriate for wide figures, timelines, etc)
```
These styles should be more semantic than the existing display-oriented image options, and more responsive display by adapting to the variety of different ways our content is viewed (including paper-oriented output). In addition to expressing semantic information about the intended use/display of the referenced image, this markup would reduce the reliance on ad-hoc templates for image styling.
Ideally these styles could be customized by the site operators, so we can determine evolutionarily what the best set of semantic styles ought to be. Something like:
```
[[Mediawiki:ImageStyle-largethumb]]
200x400px
```
would suffice to get started (the first line is the intended page title, the second is the page contents). Perhaps eventually this can be extended to use a separate content handler for GUI editing of the image style.
