How should I credit images?

to my knowledge the owner- in general *salutes*- of a picture is the always the photographer. that being said 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 show 당신 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 당신 get 이미지 from another website its usually a tad 더 많이 difficult to credit unless they actually post a credit. if 당신 have no idea who has the rights to the image 당신 can put "unknown" and put the 출처 in the description- so if anyone claims copyright 또는 KNOWS the credit 당신 can add that. i dont think anyone will pursue legal charges if 당신 screencap yourself and credit the studio. for fanart 당신 can credit the studio/owner and put the "artist" and 출처 (e.g.creative changes 의해 johnsmith456 fanpop.com)in the description. i dont think that there is need to credit the website (who does the same 당신 do: take 이미지 who belong to someone else and post them..possibly though with written permission :P) unless like i said if 당신 just add them as a source.
