change lock-dialog background?

mint 14 nadia with Mate
Are there a way to change background image of lock screen (ctrl+alt+L)? As i understood, lock screen is a part of mate-screensaver. Checked /apps/mate-screensaver/ in Configuration Editor. No luck. I found that /usr/share/backgrounds/linuxmint-nadia/gelsan_green.png is used for background (have edited it in gimp).
Any ideas?

This worked for me on mint 13, but it should work for 14 as well. Let me know if it worked for you.

change lock screen background (the lock screen when resuming from suspend)
edit the following file:
/home/user/remaster/root/etc/mateconf/mateconf.xml.defaults/%mateconf-tree.xml
find the following line:
<stringvalue>/usr/share/backgrounds/linuxmint/default_background.jpg</stringvalue>
replace “default_background.jpg” with the path to whatever image you want.

I just copied and pasted this from a guide I made for myself. Feel free to check it out. I change a bunch of stuff from stock Mint 13
