Want to use this picture in my book

Hello, can I use this image in a book I am writing on Chandrakanta Singha. Proper credits will be given.

No. User uploaded image without free to use license set in their user settings. (c) does not give you permission to use other people's photos with just attribution.

you can send PM to the contributor and ask https://en.numista.com/echanges/profil.php?id=93077

Could also have been somebody else, could even be the referee (sujit_kumar). It's just a name not necessary an account name.

Perhaps, in any case, a PM would answer the question.

Could also have been somebody else, could even be the referee (sujit_kumar). It's just a name not necessary an account name.

I'm pretty sure these are his pictures, he's not only the referee, he's also a real specialist concerning older Indian coins. Unfortunately we don't see him on the forum as much as in the past anymore . It can't be that other Sujit in Mr. Midnight's link since that one hasn't made any contributions to our catalog.

So I would send a message to him and ask. He's a very friendly and helpful guy, big chance he'll allow it.
