Hi

You can create skin easly with TrueTansparency.
Open a folder of skin you already have.
[Edit] This folder is in Program Files/TrueTransparency/Skin [/Edit]
Copy the folder and edit the name (name of your skin).
Then you have two folder: one for the window minimized and one ofr the maximized.
Use yours images and use the name who correspond to the item you want . You can modify the resolution too.
Then, edit skin.ini with notepad. it's easy, just modify the name or the font, the size, and the position of the 3 buttons.
3states mean 3 look for the button (normal, hover, clic).
The other things it's simple.
Then test, and ajust the position of yours buttons.
If my english is crappy or if you doesn't understand, ask help again here.
Enjoy
