This can also happen if someone includes an image via a http (insecure) link.

@Gaffate is it currently https?

@Minecraftpoweer ohhh. When i upload something and it directs me to the thing i posted, it probably direct me using the link with http. So it stayed that way unless i reload. Is that the case?

It is only like that when the site was "http" which was when the site kept screwing up. I Think Everything is fixed and it is back to the secure "https" Some other reason could be that somebody is having fun with MITM attacks where you make every site to "http" and then you can change the photos for everyone on your wifi etc but i highly doubt that.

Chrome tends to think everything is a threat...
