Picasa vs. Flickr

I've tried them both, but much prefer Picasa. I can edit photos (great for eliminating red eye and for cropping). If I want to post to the Web, I can preserve SOME privacy by only sending the link to those people I want to allow access. Of course, nothing prevents people from passing the link on to others, but at least it's not wide open. Flickr, on the other hand, doesn't have the same level of privacy. Plus, I find that even after using labels, I can't access the photos I've uploaded. I may be doing something wrong. Or, it may be a glitch in the tagging.
