I think you might be wrong that the image of the preimage is a subset of S. Think about the set where S = {a,b,c,d}, T={1,2,3,4}, and R={(a,1),(a,3),(b,2),(c,3)}. I think if you work it out you will find that it is S that is the subset of the image of the preimage if you try to work out R(R^-1({2,3}).

i was just wondering if the same principles of images apply with non-linear tranformations

At the beginning, do you mean A is a subset of T, or X? Isn't T the transformation? I'm a little confused...
