Comment 12 for bug 968268

So, If I want to have several wallpapers to choose from gnome-control -center I have to put then in ~/pictures? and what happens If I have dozens? and like to put them in subfolders. Is there any way in which the UI shows to me images files within subfolders?
It seems to me tha there is no practical way to choose from my recent selections of wallpapers. Its not something critical but is something so simple and basic.
