Well it's not hosting as such but similar. I really am not the best person to ask this because my account seems to have issues with that whole thing which haven't been resolved yet. Usually you should be able to access all the images that you posted via email and be able to change their security for instance (this doesn't work for me).
And I've never tried posting a gif (though mithen has, but I#m not sure if she used an external hosting service)... sorry don't know.
