4 gold coins to add to Numista [Risolto]

A good friend has 4 gold coins, which he stated I could add to the Numista website, but I would like to know how I register the photographs. I usually add my name, but as I do not own these coins, that would not be correct.

So, what should I put instead of my usual 'coinman1' signature

Also, in the 'Sources' box, what should I put in there? Should I just give credit to my friend, who wished to remain anonymous.
The four coins are listed below

Barbados 1995 10 Dollars Engagement Portrait (KM#60)
Cook Islands 1995 50 Dollars The Duchess of York with her two daughters (KM#276)
The Gambia 1996 150 Dalasis The Year of Thrre Kings (KM#61)
Guernsey 1995 25 Pounds Queen Elizabeth the Queen Mother (similar to KM#66a)

Thanking everyone in advance

Hi,

I would do it this way - you would be creating the requests huh? So just set it to: I made photographs myself, and type your friends name. Or NICKNAME, as I understand he wishes to remain anonymous.

PS: You can really write anything you like there, like "chair" or "friendidonotwanttodisclose"

Usage of "other source" is problematic, as it usually shows pictures from unauthorized source.

Jarcek,
The four gold coins were added this morning. Vern has validated the Guernsey coin already.

And now only Barbados will have to wait a week.
