The attachment is the samples of cellphone wallpapers designed from several pictures chosen from system.
We'd like to ask you whether we can use those pictures to make cellphone wallpapers? If we can, is there any regulation? And after that, can we directly choose picture samples from official website to make wallpapers?

There're a couple of samples we chose from the system which will be used as the wallpaper of the cellphone later.
Would you mind telling me:
a) if we can use these photos as wallpapers of the cellphone? If yes, is there any requirement that we should meet?
and b), if we can continue to choose samples from the official website to make wallpapers in the future?

Enclosed please find the samples for the cellphone wallpaper that we have made out of the system photos.
May we use these photos for the cellphone wallpapers? If possible, what requirements do you have for them ?
What will you say if we direct some official website photos for your wallpapers as well ?

enclosed is the sample photo that we chosed from the system and want to make it as cellphone wall paper in the future
