Blogger keeps all the blog photos. You can easily search for them using Google's image search. Does Google keep blogger.com photos forever?
Tons of people use blogger.com to create their blogs. People upload photos to blogger.com to post as photos on their blog. Well, these blogs can be viewed by anybody in the public with a couple of crafty Google searches.
Makes for some interesting searches! "Owned" pictures on blogger.com anybody?
Google Image Search: site:photos1.blogger.com owned
And yes.... there are much more interesting terms for which to search than that. Although fun, this is mainly a warning that whatever you upload to blogger likely stays in the bowels of Google image search forever.
