--[[
rawimage
Main entry point for Lua function to replace {{raw image}}
Usage:
To invoke the module directly, use
{{ #Invoke:RawImage | rawimage | pagename }}
But generally it is preferable to go through the template:
{{ raw image | pagename }}
'pagename' should be the name of a page in Page: namespace, with or without the "Page:" in front.
NOTE FOR EDITORS: rawimage displays images centred in the user's standard thumb size.
It is not recommended to offer further display options, as this would disincentivise
the replacement of raw images.
