The online photography platform has had a huge makeover and its users now get sufficient online storage for over 500,000 photos.
Flickr has undergone a massive facelift and now gives a huge amount of free cloud storage to all of its 50 million users - not just the professionals who pay to use it.
In addition to an entirely new look, the photo-sharing site has also been given an accompanying Android app for smartphones and tablets.
Chief executive Marissa Mayer said the "heart-stoppingly beautiful" layout would keep photos at their original resolution and put images at the core of the experience.
She said Flickr is "awesome again", admitting it had "languished" somewhat over time.
The free service now gives all users one terabyte (TB) of free cloud storage, with no limit on the number of photos that can be uploaded in any given time period.
Previously, unless paying for a 'Pro' account, users could only upload 300MB of images per month, and only their 200 most recent photos would be displayed on the site.
According to Flickr, the free 1TB storage is sufficient for more than 500,000 photos taken at standard 6.5 megapixel resolution. Users who need even more space can pay for a 'Doublr' account, which gives them an extra 1TB cloud storage.
The improved Flickr comes hot on the heels of yesterday's news that Yahoo!, which has owned Flickr since 2005, is to buy the blogging platform Tumblr for $1.1billion (£725million).
