gunsan,

 

First I congratulate you for winning not one, but two prizes! Heja Sverige!

 

I would say that in your case, the general rules in effect for Photos.com and/or Graphics.com must be valid. Every reasonable person understands that a photo manipulation consisting of 4-5 (part of) images or even up to 10-11 or more, can not credit every living soul. The credit is only necessary if you use the whole picture.
