I did it!!! Hell yeah!

I was reading the thread about "New Theater Mode Elements" when I found this line....
- icon element
<element type="Icon" image="Images\Test.png" mouseOverImage="Images\TestH.png" x="100" y="100" onClick="PlayPause"></element>
After some trial and error, look what I created:

I managed to add a new image element over the album cover picture.
I created a .png image of a CD Case with a transparent square inside, which will be perfectly fitting for the album art picture.
I've added this line to XBOX Music Style - Gallery.xml, adding it at the bottom of the file:
<!-- icon element -->
<element type="Icon" image="Images\cdcase1.png" x="93" yAnchor="Panel.Bottom" y="-597" width="444" height="393" min="180" max="393" onClick="PlayPause"></element>
I also changed the AlbumCover element size and position to fit the CD Case image:
<element type="AlbumCover" x="133" yAnchor="Panel.Bottom" y="-592" width="400" height="380" min="180" max="400" brightness="1.0" ></element>
I'm very satisfied!
p.s.
If anyone needs the CD Case .png files, here they go:
