There are 123 posts prior to yours, many having differing solutions. Have you tried all of the various solutions? If not, which specific one didn't work for you.I still cannot remove those files, even after following the instructions posted above!
Don't have to have the app....it's a picture sync from google and is built in and synced by default.
Go into settings----->accounts and sync---->tap google----->uncheck sync picasa web albums.
Go into settings----->application manager---->all tab----->find gallery and clear data
Make sure the synching for the Picasa albums is still off, then go into Settings > Application manager. Select the All tab, find Gallery and hit the Clear data button. Next time you open the Gallery, it will take a moment to rebuild it but the Picasa albums should finally be gone.
Agreed.
