What are Flickr favorites?

Favoriting is a way to like a photo. Favorites are an easy way to mark a photo that you like. When you mark a photo as a favorite on Flickr, the publisher is notified to let them know you like it! There is no limit on the number of favorites you can have on Flickr. You can easily revisit the photos you've marked as a favorite by mousing over 'You' which appears at the top left corner of your Flickr Homepage and by selecting 'Favorites'.
