So, in view of complaints, and the fact that my watermark is a URL, not really a "OMG don't steal my shit" sort of deal, I went and changed my watermarks.
My understanding was, I could apply the changes to the watermark in lightroom. export said images to flickr, and replace said images.
Which is true, as far as that goes. But it made new image posts. Instead of modifying the old images.
which means every fucking photo in my block? EVERY SINGLE GODAMN ONE? Is not showing.
Now, do I re-post, or edit...guh.
