- Photos from posts (Google+)
- Instant Upload (Google+)
- Drop Box (Picasa)
- 1 album per Blogger blog (Blogger)
- Blogger Pictures (appears to contain several sizes of my Blogger profile picture; Blogger)
- Profile Photo (Google Profiles)
- Scrapbook Photos (Google Profiles)
Google has a good opportunity coming up for fixing this when they re-brand Picasa to Google Photos. Also; it'd be nice if there was an option for Google Sites to do image hosting via Picasa.
