Folders added to "Desktop Pictures" not visible in System Prefs...

Question

Hello,
I am trying to add additional wallpaper images to the "/Library/Desktop Pictures" directory. I can add images to this dir and they are visible in the Desktop & Screen Saver preferences, however newly added folders are not (I would like to add folders so I can keep the pictures organized).
How do I get Desktop & Screen Saver prefs to see new folders?

Hi Mike,
Thanks very much! That did the trick!
Just so you know, there is one additional file I edited to make the folders appear with the desired name. Basically if you just add the text to Collections.plist it will display the folder but with the name on the identifier tag. If you want the folder to show a name other than the identifier you have to edit the Collections.strings file in the English.lproj directory.
Here are the instructions I've put together for this whole procedure:
--------------------INSTRUCTIONS------------------------
- cd /System/Library/PreferencePanes/DesktopScreenEffectsPref.prefPane/Contents/Resou rces/DesktopPictures.prefPane/Contents/Resources
- sudo vi Collections.plist
- add additional items in the following form:
identifier = myPatterns;
path = "/Library/Desktop Pictures/My Patterns";
showScalingPopUp = YES;
- save file and exit
THEN
- cd English.lproj
- sudo vi Collections.strings
add line entries in the following format:
myPatterns = "My Patterns";
(the tag on the left of the '=' sign must match the identifier noted above)
save file and exit
--------------------INSTRUCTIONS------------------------
The only thing I haven't been able to figure out is how to get the scaling drop-down box to appear; you know, the drop-down box that gives you the following choices on how to display the image: Fill screen, Stretch to fill screen, Center, Tile.
I see in the Collections.plist file there is a tag for showScalingPopUp and I've set this to YES on some folders, but it doesn't bring up the drop-down box when I select an image within that folder.
I can certainly live without this b/c it's not that critical, but still it's curious...
