1. under "Profile" choose Manage Photos
2. Top Right, click and choose "Edit Photos"
3. This should pull up all your uploaded pics- Click on "ORGANIZE photos" which is above your Profile photo.
4. After you have reorganized your pics, click on SAVE.
Hope this helps.
Very frustrating Dave
Make sure that when you press your left mouse button, you do not un-press the button until you have moved the photo.
