That wasn’t the one I was talking about, but I was wanting to know how to do that one too. I was talking about the one that would let you get a huge amount of cats.
It seems like ctrl.vi is broken. I noticed this a while ago. Note this was over a year ago, and I don't have the image anymore. "Only the person with the link can access." is erroneous. The way ctrl.vi used to work is you just put in an image and get a shareable link. There is no setting to change who can view. Now, that function is broken and does not work.
