How should I credit images?

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