Yahoo will be launching the Beta version of their Photo service
on Tuesday around 9AM PST. The new Yahoo Photos service will have a lot of AJAX so that everything will flow smoothly and impress people (just like AJAX always does).
They will also have a few new features with the release. One of the new features will be Smart Albums which will automatically create albums based on tags, ratings, date, and more. This way you can always have it create albums of your highest rated photos without needing to manually create the album yourself. This is similar to software like iTunes that will automatically create playlists of your most played songs, newly added songs, etc… which is becoming an increasing popular feature.
