I'm assuming your trying to change the background image to the Home page of the Project Mayhem III skin.
If so, first are you displaying High-Def or Standard?
If High-Def you need to edit the home.xml in the PAL16x9 folder found in the Project Mayhem skin directory.
If your displaying standard resolution, then you need to edit the home.xml in the PAL folder.
Create your background image and transfer it to the "Media" folder found in the Project Mayhem III skin directory.
Then open the appropriate Home.xml file and look for this control:
<control type="image">
<description>background image</description>
<posx>0</posx>
<posy>0</posy>
<width>720</width>
<height>576</height>
<texture>
16x9home2.png</texture>
Change the text highlighted in red to the name of your new background image file, and reboot. The text in red will differ in name depending on whether your in the PAL or PAL16x9 folder.
If you want to see all the PMIII textures in their uncompressed format, then you can download the entire skin from the XBMC SVN. From there you can explore the entire PMIII skin, just don't go ripping Chokemaniacs images without his authorization.
To get the skin from the XBMC SVN, first install this app:
Tortoise SVNHow to use Tortoise after installation:
1) Rightclick the folder where you want XBMC source folders & files to be downloaded.
2) Choose: 'SVN Checkout'.
3) Enter 'https://svn.sourceforge.net/svnroot/xbmc/trunk/XBMC/skin/Project Mayhem III' as "URL of repository".
4) Hit OK.
IMPORTANT NOTE: The URL listed for the XBMC SVN is for the PMIII Skin ONLY, and is about 45MB's. Theres no need to download the entire SVN if you just want to view the PMIII textures.This post has been edited by xboxbox451: Jan 12 2007, 08:28 AM
