[OLPC library] [support-gang] Image sizes on the wiki was: working hard @ Boston's

[Samuel Klein]

I think it is easier to just upload the high res version once, even if
you explicitly mean to use one of the smaller versions for some
offline project.

Fred - you are right that the /directory trees/ of thumbnails are now
not browsable,but all of the individual thumbnails are world-readable.
