is it possible to enlarge the album artwork?
If this is not possible, could the artwork panel be enlarged by manipulating the skin settings? How to do it?
It's only possible by editing the skin.
After unpacking the skin you will need to change the size of the cover.png for whatever you want in the folder CoverBig.
Then you need to edit Skin.xml: change SkinLayouts Save="1" to 0. Find Layout Name="Playlist" change Position Right="[your size+2]" (in my case the cover is 284x284 so the value of the position is 286).
Find Layout Name="Big Cover" change Position Width="[your size+1]".
Find Layout Name="Spectrum" change Position Width="[your size+1]".
Find Layout Name="Lyrics and Small Cover" change Position Width="[your size+1]".
Now you need to change the positions of the stuff bellow the cover:
Find Layout Name="Big Cover" bellow that you'll see Artist, Title, Album and Rating. Change the values of Top= You'll have to figure out your values.
Do the same with Layout Name="Spectrum" and Layout Name="LyricsOffButton"
Test your skin, when finished change back SkinLayouts Save="0" to 1 and version to 1.5
