Well I was going off what the above parent comment was saying, that recent advances in compression + cheaper hosting should make it more viable. I don't know much about what any of those costs cause I've never run anything that needs a lot of serving costs at scale. So I'm guessing even with that it's still too expensive?
On the other hand, I think Imgur also pushed way more traffic upon itself by trying to make itself into another social media site. Like, if it just stayed an image host it probably could have stayed more niche and wouldn't have had thousands of casual internet users scrolling through images all day at work.
