Flickr is intended for personal use and is not a generic image hosting service. Professional or corporate uses of Flickr are prohibited.
所以 Flickr 只限於個人使用。
The Flickr service makes it possible to post images hosted on Flickr to outside websites. This use is accepted (and even encouraged!). However, pages on other websites which display images hosted on flickr.com must provide a link back to Flickr from each photo to its photo page on Flickr.
不管是何種用途，你必須注意到 Flickr 要求要有 link 指回原來的那張圖。
Your account will also be terminated if it is used for hosting graphic elements of web page designs, icons, smilies, buddy icons, forum avatars, badges and other non-photographic elements on external websites.
不能拿來放 icon、banner 或是其他之類的。
