It's set to show the new pics in the last 24 hours, but you can set it to the last week, last month, last year, or forever.
You can also change the "new" to "popular" to see the photos in order from the most-liked on down.
You can choose to look at pics from just 1 kind of plant. It's very fun to browse pretty pics. I do it constantly, while watching TV, down time @ work, etc...
