Of late, there has been lots of issues / problems with image hosting sites like imgur and imageshack. Some of them suddenly change their ToS like imageshack which went premium and imgur which is down frequently. I believe they had at least 5 or 6 outages during 2015. Some of the outages took them forever to retrieve. Latest is, being a file sharing / image sharing site they land up on the wrong side of law frequently. Atleast in India they were banned few times by Court rulings. Like this here Even now for some reason imgur is down here in this part of the world, while it is opening with a proxy. Looks like another ban by ISPs. I am unable to see any sales thread images. My suggestion is to let users load the images from their hosted domains or offer a wide range of file sharing sites to host their images.
