Thank you for that (and sorry for leaving earlier) but I can't see how does that solve the issue of translating the whole image. For example, if I want to translate the whole image in the x direction by 5 pixels say, I still have to do something a kind of T_img = img[1:x + 5, :], which is not possible. And you can't do things like new_img = img[a:b, c:d] anymore to pick only part of the image.
Edit: well, it does work for [[1:x] + 5, :] if I change mod1 by mod though, good! Thanks!
