I came across this question and in the process found that I could not access the corresponding image as it was hosted on imgur. Is there any solution for the above? (The questions contains a link image which has been probably now been deleted by the imgur site.) The imgur policy on deletion of images is
As long as images are getting at least 1 view every 6 months, they will stick around forever. After that, your image may be removed to create more space for newer images.
In that sense, can there be a feature designed so that the images linked to imgur are visited every 5 months or so by the site itself? Or should we systematically discourage people to use links to images as such as instead ask them to upload the image using the Image function of the stackexchange software?
