Cost: Free for 1 GB of photos and videos (files under certain size limits don’t count); from $2.50 a month for additional storage.
How it works: Download the desktop version of Picasa. It scans your computer for all your photos, then lets you choose the ones you would like to put online. You’re allowed 10,000 albums and can upload 1,000 photos to each. Click the Shop button to order prints, CDs, books, cards, and more.
Cool perks: The I’m Feeling Lucky button lets you crop and remove red-eye from a batch of photos in a single click. Other fun editing features: adding music to photo slide shows and altering photos to appear black-and-white, matte, or sepia-toned.
Drawbacks: Since Picasa recently merged with the Google+ social network, keeping your images private can be tricky.
Best for: Those who are comfortable using Google+, since the sites are closely integrated.
