In vs. on: Although there is use for both forms, it sounds better to say "in your project". That is, your photographs are becoming a part of this project, so they are in it rather than on it. There is no hard and fast rule on this, however. You can say:

I am in choir.

I am on the Executive Board.


"In your project" sounds correct to me.
