Person I reblogged this from had tagged it “source unknown”, but as it happens, it actually had a proper clickthrough link coded. I still can’t figure out how to add or change them in the new reblogging interface. Pah.
(argh, I could have sworn I found a way to add/change click-through link by, like, clicking on the upper right corner of the photo, sort of like getting to an individual post page from the dash. doesn’t seem to be there now. doesn’t work in Chrome either. the gear only includes content source, not clickthrough link. feh.)
