Thanks for the advice guys, so i will submit these photos as editorial, i am happy 'cause it was a pity to do not submit some nice pics of people i did in Africa. And thanks for the compliments, i really appreciate it!
@Marco, I am happy to receive your comment, i follow you since you started and i find your works so great and unique! Master!
Actually, you do not need them to be newsworthy. Just upload as editorial. Because there is no signed release, they can not be used as advertisements. But, they can appear in books and magazine stories.
Marcomayer is right; upload them as editorials. You only have to find a news usefulness for them and explain that in the description area (it's easy, it tells you everything when you edit the upload). Good luck!
