Thanks to all, I just need the code necesary to put a contact list background on version 9.0, but i really need assistance cause i dont know what to put in the styles/definitions files, so i ask you guys, How could be the code for a skin with this conditions:
1. Compatible for both 8.5 & 9.0 versions
2. Change the main windows pictures
3. Background on contact list

I´m trying to read the skinning documents but its a little hard for me cause i dont speak english, writing this post took me about half an hour, I really apreciate what you´re doing.
Thanks to all
