We're a community of many types of people, who all have the right to feel comfortable and who may not think what you think, believe what you believe or see what you see. So, be polite and respectful in your interactions with other members.
他の人の著作権を尊重しましょう。要するに、他人が撮った写真を盗用したり、それらを自分の物にみせかけたりなどはしないでください。それから、Flickrは写真を載せるためのものです。他の画像ファイルを投稿することも少しぐらいの例外としてOKではありますが、あなたのフォトストリームのファイルの大多数が写真以外のコンテンツ（イラストレーション、コンピューターのスクリーンショット、グラフ等）で占められているような場合には、あなたのアカウントはNot in Public Site Areas (NIPSA)指定される可能性が大きいです。NIPSA指定されると、あなたの写真が写真検索対象として挙げられず、自分のページと、グループ、コンタクトからだけ見ることができます。
Upload photos that you've taken
Respect the copyright of others. This means don't steal photographs that other people have taken and pass them off as your own. And yes, Flickr is for photos. With some exceptions, it's OK to post other images, but if the majority of your photostream contains content other than photographs (like illustrations, screenshots, diagrams, etc.) it's very likely that your account will be marked Not in Public Site Areas (NIPSA). NIPSA means your photos won't show up in photo searches, but they will still be visible in your pages, your groups and contacts.
Link back to Flickr when you post your photos elsewhere
The Flickr service makes it possible to post images hosted on Flickr to outside websites. However, pages on other websites that display images hosted on flickr.com must provide a link back to Flickr from each photo to its photo page on Flickr.
Upload photos that include frontal nudity, genitalia or anything else that your bathing suit should cover in public areas of Flickr
If you do we'll make your photostream private and remind you of this Guideline. If you don't heed our warning and continue to make similar content public, we'll terminate your account without warning. This applies to your Buddy Icon as well.
Upload content that is illegal in public or private areas of Flickr
If you do, your account will be deleted and we'll take appropriate action that may include reporting you to the authorities.
You will see all sorts of things on Flickr, some of which may offend you. If you are offended by a photo you can either click away from the photo or you can flag it as "offensive" by clicking on the "May offend" link next to every photo. If you think there's immediate cause for concern, you can report content and/or someone's behavior to Flickr Staff.
If you see your photographs in other members' photostreams, don't panic. This is probably just a misunderstanding and not malicious. A good first step is to contact them and politely ask them to remove it. If that doesn't work, please file a Notice of Infringement with the Yahoo! Copyright Team who will take it from there.
You may feel tempted to post an entry in one of our public forums about what's happening, but that's not the best way to resolve a possible copyright problem. We don't encourage singling out individuals or their photos in our public forums.
We don't want these parameters to be a downer and we want everyone to have a good time. If you don't feel that you can abide by our Community Guidelines as outlined above, maybe Flickr isn't for you. Plainly speaking, if you don't want to abide by our TOS and these Guidelines, don't let the door hit you on your way out!
If you ever have any questions or comments, we'd love to hear from you. Please feel free to drop us a line through Flickr Help by Email.
