Resizing / repositioning the pictures for the edges of all boxes

Oops, I’ve forgotten to link the package I meant. I’ve edited it.


But thank you very much for the quick response. I already feared that it won’t work for all windows at the same time.

An additional Question: I guess that changing the position of the close button in the upper right corner would be the same problem, right?

Well, than I guess I will have to find another way to implement my ideas.
