After recently updating to UP5 using Mint Update on an ASUS eeePC, curiosity prompted me to to try this:
I then tried them to see what they looked like but decided I preferred my 'Debian' look as a background (BTW both of the 'gelsan' backgrounds are LM13/Maya - not LM14/Nadia).
When I went to Settings > Desktop > Backgrounds to change back to it, the image is no longer listed (it was listed as 'Default' I think after the update but before I fiddled). Synaptic shows I have both the mint-backgrounds-debian and mint-backgrounds-xfce packages installed so I know it must be somewhere (probably hidden) but have no idea where to look to locate the image to re-add it to the list. Can anyone help?
