So far we have no information about image sizes in Parsoid, and will need to perform API queries to retrieve this information. We will also have to retrieve the configured default thumbnail size (if available) through the MediaWiki web API.

I'm classifying this as low priority for now as our normal priority bugs concern basic editing and round-tripping.

This seems very similar to bug 50523. We set the mw-default-size class; VE should be observing this when it applies display styles. (The current default image size should probably not be hardcoded into the DOM representation.)

We have since changed the default to 220px, but still don't have access to the configured default thumb size in the wiki. We should probably expose $wgThumbLimits[ $wgDefaultUserOptions['thumbsize'] ] in the siteinfo api end point, and then use that for rendering.
