We have 87 photos uploaded so far, and they all pretty much seem to be on-topic too!: https://commons.wikimedia.org/wiki/Campaign:WikiPixNC
Not sure if it might be worthwhile to actually tweet or use the #WikiPixNC hashtag, if anyone might be into that kind of thing. There aren't any mentions on Twitter yet, but maybe one could seed it a bit.
Thanks, Richard (User:Pharos)
