please mind your language.

You seem to assume everything to your liking. The modeler has already said that the texture is of 1024x1024 and yet you assume that it is of 512x512.
When I say that I am not going to re-uv or anything that you know of then still you insist that I am wrong. I think that you should appologise for this. You could challenge me by sending any model and see what I can do with it. Instead you talking [censored].
