So this is what I understand, you have an album folder with pictures in it and you want there to be a misc picture shown on the folder in XBMC?
Easy (except for you have to pick a picture you want displayed)
1) take the picture you want to be displayed on the folder and rename it to "folder.jpg" literally (you might want to copy the picture and rename it so that you can keep the name of the existing picture as well). XBMC willr econize the folder.jpg as a thumbnail and will show it on the filecover
2) resend back to your xbox (dvd,cd,ftp,stream)
3)make sure you set up the my pictures settings correctly in XBMC (self explanitory)
hope this helps

I think you can scan your picture file on the xbox (create thumbnails) and then it iwll make a miscelanious thumbnail for the folder.....but dont quote me on this, I am not sure, the above method does work though....
