Imgur 的使用條款，其實禁止你用它來當圖床

雖然一大堆網站與服務使用 Imgur 當圖床

比如 JPTT 的圖片上傳就直接放在 Imgur

但其實他的使用條款有明訂禁止這麼做

Also, don't use Imgur to host image libraries you link to from elsewhere, content for your website, advertising, avatars, or anything else that turns us into your content delivery network. If you do – and we will be the judge – or if you do anything illegal, in addition to any other legal rights we may have, we will ban you along with the site you're hotlinking from, delete all your images, report you to the authorities if necessary, and prevent you from viewing any images hosted on Imgur.com. We mean it.

口氣非常嚴厲的警告不要這麼做

國外網友也多次討論過這件事

While Imgur is an image hosting service, their service is intended for the images to be commented upon, rated and shared within that site by members of their community.
