Windows 7: Skydrive publishing from Windows Live Gallery

Now, I understand that once you install the Skydrive PC program, you get a folder on the desktop. Whatever is in that desktop folder, however the contents are organized--that's what gets synched up to the SkyDrive Interwebs.

Which means that my entire photo collection, all 13GB of it, needs to be copied into the desktop SkyDrive folder...right?

Now, I also have a Windows Live Photo Gallery on here- never used. But I see on there,that there is a thing that says 'publish to SkyDrive.' Does that mean if I hit the button, they are automatically copied there? So I don't have to dupe my collection?

I pushed the 'Publish to SkyDrive' button, and it appears grayed out. WhatamIdoingwrong?

Your question is about Live Photo Gallery, not Windows 7. If you have installed the SkyDrive software OK you will have a new SkyDrive folder in Explorer or whatever file manager you use. So you can just copy/past whatever you want just like you would to a "real" folder on your hard drive.

I'm guessing the Live Photo Gallery doesn't use the same file access code as Explorer - but I don't have that software so can't be sure.
