Unable to find aperture library when set up wallpaper

Question

This has stuggled me for around a year, ever since i upgrade to lion when it is available, i found its hard for me to change my wallpaper to the images located in my aperture library.It's simplely not showing up as a available option in the preference panel desktop image section.
No offense, but dont tell me to do the repair disk, repair permission thing, or change the preview as "always" in the sharing section.
This is what i've done:
1>I've done format the entier hard drive "7 pass erase" around 3 times
2>Fixed the permission, repaired disk, runned daily weekly monthly script for thousands of times.
3>Reinstalled the OS thousands of times.
4>Repair Permission, Repair Database, Rebuid Database for Aperture 3 thousands of time.
5>Runned ACL repair under recovery mode 3 times in Apple Terminal.
6>Called Apple Support, reached to 3 different senior technicients
7>Done the research online
8>Tried everything i can.
I like photography, and i have a 70G aperture library. now i can only export the image into a folder and choose the image from the folder to do it. I know I know, It's not a big deal, just wallpaper. I'd done some programing for 2 3 years. It's kind of a habbit for me to debug the thing, i feel like this is issue for me, which makes me uncomfortable. Can anyone tell me how to fix this or have any clue?

Answer 1

Have you tried putting your pictures in this folder:
I just tried two things: putting a folder into the Pictures folder did not result in any pics showing in the Preferences Pane; however, putting individual pics in that folder worked - they showed up in the Pane immediately.
