SkyDrive doesn’t allow you to synchronize any folder on your computer, only folders inside a special SkyDrive folder.
SkyShellEx Utility adds a right-click option to add ANY folder. Choose your version of Windows (either x64 or x86 bit for 32-bit). You may have to update your .NET Framework to 4.0
After installing, just right-click on a folder (not a single picture) and choose, ‘Sync to SkyDrive’. Synchronization will then begin.

That’s it. Just check your online SkyDrive to make sure the pictures did indeed sync.
