I just wanted to write a comment with reference to an image. As comments won't allow inline images, I uploaded the image to an edit window of some other post, canceled the edit there, and included the URL in the comment instead. Now I wonder whether this image is going to stay around, or whether it will vanish in the near future after some automated process finds out that no core post includes that image. Can you tell me?
According to this post the images uploaded from StackExchange will stay on Imgur as long as StackExchange keeps up their pro account.
