Hey guys. I finally found how to stop this stupid tool from uploading pics automatically. I was so relieved to find this solution because Picasa was starting to upload pics that I don't even remember taking.
On your phone:
go to---->
1) settings
2) accounts and sync
3) click on your gmail account
4) uncheck Sync Picasa Web Albums (and for good measure if you want also uncheck Sync Instant Upload and Sync Google Photos)
5) now hit back and sync all
Now go into your gallery and the folder that says 'Instant Upload' should be gone.
I hope this helped
