When logging in lubuntu 12.04, my background image always disappears, leaving the screen with color only and then I have to go to definitions and set the image in the background again.
I notice that this does not happen with low-resolution images, only with high ones, but also happens with images that fit my screen resolution (1280 X 720).
Any ideas on how to fix this?
The image remains at it's location, but on the desktop preferences, the pathway to the file location is lost and set to none
.

I had the same problem. When I login, I get a black screen as if the image has been deleted. Then I figured out that it was a permission issue. So I went into the permission tab, and changed Group, and Other permissions to Read and Write, and that fixed it.
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.
When it comes up navigate to
/usr/share/backgrounds
and change the permissions from the permission tab.
