How should I credit images?

to my knowledge the owner- in general *salutes*- of a picture is the always the photographer. that being 発言しました in most cases i think they give the right to the company so "20th century fox" is okay as a credit.
if youre unsure who produces/owns the right to the tv 表示する あなた can always check imdb.com (same for movies)since i think for movie stills they always give the rights to the studio as well.

if あなた get 画像 from another website its usually a tad もっと見る difficult to credit unless they actually post a credit. if あなた have no idea who has the rights to the image あなた can put "unknown" and put the 情報源 in the description- so if anyone claims copyright または KNOWS the credit あなた can add that. i dont think anyone will pursue legal charges if あなた screencap yourself and credit the studio. for fanart あなた can credit the studio/owner and put the "artist" and 情報源 (e.g.creative changes によって johnsmith456 fanpop.com)in the description. i dont think that there is need to credit the website (who does the same あなた do: take 画像 who belong to someone else and post them..possibly though with written permission :P) unless like i 発言しました if あなた just add them as a source.
