I have just tried to upload an image on Puzzling (although have checked and it is happening in both chat and on other sites) and it generated a link to a picture I have never seen before.
It doesn't matter what picture I upload, I get given the same image.
This is also happening for other people, so there seems to be a bug.
This is the image I keep getting, and not only is it not on my computer, but I uploaded a completely different picture in this very post. However, I am now getting a different image when uploading something, and it appears to be changing every 10 minutes or so...
