Wallpapers disappearing in Cinnamon

[krespim]

Hi all,

I've recentely installed Ubuntu 12.04 LTS 64-bit and installed Cinnamon. Originally the wallpaper that I've choosen was this:
http://imagecdn.maketecheasier.com/2012/03/cinnamon-desktop.jpg


But for some reason, I suspect some update, this wallpaper was replaced and I cannot find it in my systems. Does anyone know where I can find it again?

Another wallpaper that I fancy is this:

http://www.linuxmint.com/tmp/blog/1910/2.png

Yes, I know is Mint, but I am molecular Biologist after all and It would great to have it. Again, any ideias on where to find it?

I've tried to google it and search in this forum but would not find the answer to my (silly) questions. So be gentle and please help me.

Cheers!

You may have to look for a while, but this is a great place to start.
