I guess I really like the desktop application and having the ability to view the photos on my computer easily when offline. Also in Picasa, you can easily see which pictures have been uploaded already, whereas with Flickr, once you upload a folder of pictures and add more pictures to that folder later, you’ll have to go to the web site and check which ones you already (at least I think).

It is very easy to upload photos from your computer to Flickr. You can either use their official uploading tool – http://flickr.com/tools/ – or you can use their newly-redesigned web interface – http://flickr.com/photos/upload/

It can’t get any easier!
