Okay so I have just made my first skin, (yay whoopie!.. okay good feeling gone) and I have some problems. I've been reading now for like an hour and I'm getting no where. This is the code I've done so far,

<SkinInfo>
   <Information>
      <Name>Half-Blood Prince</Name>
      <Description>I have taken my Harry Potter obsession to a new level!
I'm not sad, I'm just dedicated. </Description>
      <Version>1.0</Version>
      <Compatibility>
         <MsgVersion Major="8" Minor="5"/>
     </Compatibility>
   </Information>


   <MessengerSkin>
      <ResGroup>
         <Restrictions>
            <MsgVersions>
               <Version Major="8" Minor="5"/>
            </MsgVersions>
         </Restrictions>
         <Resources>
             <Replace>
                <Graphics>
                   <Pictures>
                      <Picture Id="20061">
                        <File>images/20061.png</File>
                      </Picture>
                   </Pictures>
                </Graphics>
             </Replace>
         </Resources>
     <ResGroup>
   </MessengerSkin>
</SkinInfo>

Now its not a very long code, because all I want to edit is the background of the sign in window. So far that has worked,


(image has been made smaller so it loads)

and I'm pretty happy with that image

But then when signing in, its actually changed a bunch of images. I know why I just don't know how to edit it so only the background of the sign in window is changed. 







help?
